[0063] The embodiments of this disclosure will now be described in detail. When the description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0064] It should be understood that in the description of all embodiments of this disclosure, the terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Terms such as "coupled" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication; they can refer to a direct connection or an indirect connection through an intermediate medium to form a linkage relationship; they can refer to the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in this disclosure can be understood according to the specific circumstances.

[0065] In the various embodiments of this disclosure, the symbol " / " indicates that it has two functions simultaneously. The symbol "A and / or B" indicates that the combination of the preceding and following objects connected by the symbol includes three cases: "A", "B", and "A and B".

[0066] The following is combined with Figure 1 The working environment system of the intelligent wall switch involved in this invention is described. This system provides the operating environment and implementation basis for the various control methods of the intelligent wall switch.

[0067] like Figure 1 As shown, the system includes: smart wall switches, terminal devices, relay devices, and cloud servers.

[0068] The smart wall switch is capable of communicating with the terminal device. It is suitable for installation in power lines and can be used to control high-voltage loads. The smart wall switch has at least one screen for display. Furthermore, it has the ability to control the on / off state or adjust high-voltage loads (such as lights, fans, and motorized curtains) via relays or SCRs. The smart wall switch can establish a communication connection with the user's terminal device to receive instructions or data from the terminal device.

[0069] Specifically, the smart wall switch described in this disclosure is an electrical control device that integrates display and interactive functions. It is installed in a standard wall box (e.g., type 86 or similar) and positioned between the mains power line and the high-voltage load.

[0070] In this embodiment of the disclosure, the terminal device may be, for example, a user's smartphone, tablet, or other mobile terminal with computing and communication capabilities. The terminal device has a dedicated application (App) installed, through which the user can browse, select, or manage the interface style scheme of the smart wall switch and / or personalize the user interface of the smart wall switch.

[0071] The cloud server refers to a server system deployed in the Internet cloud for storing and managing interface style scheme data, processing terminal device requests, and interacting with relay devices.

[0072] The relay device refers to a device deployed in the user's local network environment that can realize communication forwarding between the cloud server and the smart wall switch, such as a smart home gateway, router, etc.

[0073] Taking the relay device as the gateway device as an example, the smart wall switch and the gateway device establish a connection using short-range wireless communication protocols (such as Zigbee and Bluetooth Mesh) for transmitting detection status, receiving commands, and reporting event information. The gateway device and the cloud server connect to the internet via a home router, using IoT protocols such as MQTT, HTTP, or CoAP for bidirectional communication, enabling data uploading and command distribution. The terminal device and the cloud server connect to the internet via a mobile network or Wi-Fi, using secure protocols such as HTTPS for data interaction. Users can perform corresponding operations on the application, and data is synchronized to the gateway device and the smart wall switch via the cloud server. In a local area network environment, the terminal device can also communicate directly with the gateway device via local network protocols to achieve local control of the smart wall switch, reducing cloud dependence and improving response speed.

[0074] In some solutions, the communication between the smart wall switch and the terminal device can take at least one of two paths: a remote control path and a local direct connection path.

[0075] The remote control path involves the terminal device connecting to a cloud server via the internet, and the cloud server forwarding instructions to the smart wall switch via a relay device (such as a home smart gateway).

[0076] The local direct connection path involves establishing a point-to-point wireless communication connection (such as Bluetooth direct connection) between the terminal device and the smart wall switch. This path avoids multiple forwardings of data through cloud servers and gateway devices, improving transmission efficiency and reliability.

[0077] In some solutions, the smart wall switch also has human body sensing capabilities, which can detect whether there is a human body within the detection range and then execute corresponding control logic.

[0078] It should be noted that the above system is only an exemplary implementation method, and can be adapted to meet product requirements and network environment in practical applications. Any modifications and substitutions that do not depart from the concept of this invention should fall within the protection scope of this invention.

[0079] Furthermore, the technical features involved in the various embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0080] like Figure 2 The diagram shown is a block diagram of a smart wall switch according to an embodiment of this disclosure. It can be seen that the smart wall switch includes at least a button, a screen, an on / off module, and a processor.

[0081] The buttons are used to receive control input. Users can operate the buttons by pressing, touching, or other means. Types of control include, but are not limited to, short presses, long presses, double-clicks, and swipes (for touch buttons). Different control types can trigger different functional responses; for example, a short press controls load on / off, while a long press enters network configuration mode.

[0082] The screen is used to display button identification information; the button identification information is used to indicate the button. The button identification information can be text, an icon, or a combination of both, used to tell the user what function the current button corresponds to. For example, displaying the text "Living Room Light" or a light bulb icon next to the button allows the user to immediately understand that the button controls the living room light.

[0083] The switching module is used to connect to a power line and can be controlled to be switched on or off to control the on / off state of the high-voltage load in the power line. The switching module is a component inside the smart wall switch responsible for actually switching on or off the high-voltage line. Exemplarily, the switching module includes at least one of a relay, a silicon controlled rectifier (SCR), or a solid-state relay.

[0084] Taking a relay as an example: A relay has a coil and contacts. When the coil is energized, the contacts close, and the circuit is connected; when the coil is de-energized, the contacts release, and the circuit is disconnected. Smart wall switches are usually connected in series with the live wire. The two ends of the relay contacts are connected to the incoming and outgoing wires, respectively. When the user presses the button, the processor controls the relay coil to be energized or de-energized, thereby realizing the switching control of high-voltage loads such as lights and fans.

[0085] The processor is electrically connected to the screen, the on / off module, and the button, and is configured to control the on / off module to be turned on or off when the button is operated.

[0086] Specifically, the processor can be, for example, a microcontroller (MCU) running firmware. The processor detects changes in the button's state and executes corresponding logic based on the type of button press, such as controlling the engagement or disengagement of a relay or refreshing the screen display. Simultaneously, the processor also communicates with terminal devices (such as mobile apps), receiving configuration commands and updating local parameters.

[0087] In some embodiments, the processor can directly drive the screen. In this approach, the processor's GPIO pins or a dedicated LCD interface are directly connected to the screen's driver pins, sending display data via software simulation or hardware SPI / I2C timing. For example, when using an OLED screen, which typically has a built-in driver chip (such as the SSD1306), the processor can control the screen's display content by sending commands and display data to this driver chip via the I2C or SPI bus. This method is simple in circuitry and low in cost.

[0088] In some embodiments, the processor can drive the screen using a dedicated screen driver chip. For example, when the screen is an LCD screen, the screen driver chip (such as an LCD controller) can independently handle the video memory management and refresh tasks, separate from the processor. The processor only needs to send the content to be displayed to the screen driver chip through a parallel interface or SPI, and the screen driver chip automatically processes the timing and drives the screen display.

[0089] In some embodiments, the processor is further configured to:

[0090] Receive a location configuration instruction; the location configuration instruction is generated by the terminal device in response to the selection of one of a variety of preset display locations, based on the selected preset display location;

[0091] In response to the location configuration command, the display position of the button identification information on the screen is adjusted so that it is located at a preset display position.

[0092] Understandably, small screens (e.g., screens smaller than 3 inches) are suitable for wall-mounted devices requiring a compact design, such as smart wall switches. In this case, button labels will occupy most of the screen, directly impacting the visual experience. If the button labels are always displayed to the left while the switch is on the user's right, it might feel awkward; conversely, the opposite is also true. Therefore, allowing users to adjust the display position accommodates different installation locations and usage habits, improving the user experience.

[0093] For example, the preset display position includes at least one of a left-side display position, a center-side display position, or a right-side display position. The screen uses a 0.96-inch OLED screen, such as... Figure 3 As shown, the mobile app offers two options: "Left Alignment" and "Center Alignment". When the user selects "Left Alignment", the button names and icons are aligned to the left; when the user selects "Center Alignment", all content is displayed in the center of the screen.

[0094] In some embodiments, the button identification information includes a button icon and / or a button name. The button icon is a small image or symbol, such as a light bulb, fan, or socket; the button name is text, such as "living room light" or "bedroom light." In some solutions, users can choose to display only the button icon, only the button name, or both, according to their preferences and usage habits.

[0095] Furthermore, the processor is also configured to be able to:

[0096] In response to the received icon layout configuration instruction, the relative position of the button icon and the button name is adjusted so that the button icon is located at the preset end of the button name; the icon layout configuration instruction is generated by the terminal device in response to the user selecting one of a variety of preset icon layout methods; each icon layout method represents a specific relative positional relationship between the button icon and the button name.

[0097] Furthermore, users can flexibly adjust the display method according to their visual habits or wall installation location (e.g., switches are installed at different heights or angles) to make button label information easier to identify.

[0098] For example, the settings interface of a mobile app may provide at least one of the following layout options:

[0099] Icons on the left, text on the right;

[0100] Icons on the right, text on the left;

[0101] Icons on top, text on the bottom;

[0102] Icons at the bottom, text at the top, etc.

[0103] After the user selects one of the options, the app generates the corresponding icon layout configuration command and sends it to the smart wall switch via Bluetooth or Wi-Fi. Upon receiving the configuration command, the processor redraws the screen display area, arranging the button icons and names of each button according to the selected relative positions and refreshing the display.

[0104] In some embodiments, the button identification information displayed on the screen includes button icons.

[0105] The processor is also configured to:

[0106] In response to the button being pressed, the currently displayed first icon data is switched to second icon data at the same display location on the screen; or,

[0107] Switch the currently displayed second icon data to the first icon data;

[0108] The first icon data and the second icon data have the same icon outline, and visually distinguish between the wireframe state and the filled state.

[0109] Specifically, the smart wall switch stores two image data sets for each button icon: one is a wireframe (only outlines, the interior is empty), and the other is a filled image (the outline is filled with solid lines). The outlines of these two images are exactly the same; only the internal filling differs. For example... Figure 4 As shown, when the button icons on the screen display wireframes, if the user presses a button, the processor switches the button icon corresponding to that button from a wireframe to a filled image; when the button icons on the screen display filled images, if the user presses a button, the processor switches the button icon corresponding to that button from a filled image to a current image. Because the switching speed is very fast, the user will feel as if the icon has been "lit up," and will receive very intuitive feedback that the button has been pressed.

[0110] Since the contrast between the outline and the fill can be clearly distinguished without color, and since the icon outline remains unchanged, there will be no flickering or jumping sensation when switching, this solution is suitable for smart wall switches with black and white screens.

[0111] Furthermore, in some embodiments, the button icons of each button can be freely selected by the user through the terminal device, and the button names of each button can be freely edited by the user through the terminal device.

[0112] For example, such as Figure 5 As shown, users can individually set the button icon and name for each button on the mobile app. After opening the app and connecting to the smart wall switch, the settings interface will display the settings for each button in the current working mode of the smart wall switch. Clicking on the icon setting in the settings for any button will bring up an icon library in the app, containing various common icons such as light bulbs, fans, sockets, curtains, speakers, air conditioners, humidifiers, and robot vacuums. Users can directly select a preferred icon. After selection, the app will send the icon's binary data or image URL via Wi-Fi or Bluetooth, allowing the smart wall switch's processor to receive and store it locally, immediately refreshing and displaying the new icon on the screen.

[0113] To edit the button name, users can click the text input box for the button name to bring up the soft keyboard, where they can freely enter any text, such as "living room main light", "bedroom spotlight", "away mode", "one-click turn off the light", etc. The maximum length is 10 Chinese characters or 20 English characters.

[0114] Through the above solution, each user can customize unique icons and names for the buttons of the smart wall switch according to their own preferences and the actual situation of their home devices, making the switch panel more intuitive and personalized.

[0115] In some embodiments, the button includes:

[0116] The first type of button is configured to generate displacement in response to a pressing operation to trigger a mechanical switch signal. Specifically, the first type of button includes mechanical buttons. For example, a mechanical button may include a keycap that can move up and down and a tactile switch or dome switch on a circuit board below. When the user presses the keycap, the keycap moves downward a certain distance, pressing the tactile switch. The spring inside the switch closes momentarily, generating an electrical signal (mechanical switch signal) to the processor. After the keycap is released, it returns to its original position, and the switch opens.

[0117] The second type of button is configured to generate a touch switch signal in response to a sensing operation. Specifically, the second type of button is a touch button. For example, a touch button can be a capacitive touch button, with a capacitive sensing pad below the touch button area. When a user's finger approaches or touches the pad, the parasitic capacitance between the finger and the pad changes. The touch detection chip detects this capacitance change and outputs a sensing signal (a touch switch signal). Touch buttons have no moving mechanical parts, no travel distance, and are triggered with a light touch.

[0118] Furthermore, the processor is also configured to be able to:

[0119] In response to the mechanical switch signal, the on / off module is controlled to be turned on or off;

[0120] In response to the sensor switch signal, the screen is controlled to switch the displayed content.

[0121] Specifically, the first type of button is responsible for high-voltage control. When the user presses a mechanical button, the processor toggles the relay's state. The second type of button is responsible for switching the screen's interface. When the user touches a touch button, the processor switches the displayed content to the next group, such as switching from displaying the button name in relay mode to displaying the scene name in scene mode. The two types of buttons perform their respective functions without interfering with each other.

[0122] In this way, users can use the mechanical buttons for a solid tactile feel to turn the lights on and off, and use the touch buttons to switch the content displayed on the screen, without worrying about accidental touches causing changes in the lighting.

[0123] Furthermore, the processor is also configured to be able to:

[0124] In response to the sensor switch signal, the working mode of the smart wall switch is switched;

[0125] The working mode includes a first working mode and a second working mode. In the first working mode, all the first type of buttons are used to control the on / off module. In the second working mode, all the first type of buttons are used to trigger a preset linkage operation.

[0126] Specifically, when a user touches the second type of button, the processor not only switches the content displayed on the screen, but also changes the overall working mode of the switch.

[0127] For example, a smart wall switch has four first-category buttons. In the first operating mode, these four first-category buttons control the lights in four rooms respectively. When a user touches a second-category button, the smart wall switch switches to the second operating mode. At this time, the screen displays the scene name corresponding to each first-category button (such as "Away Mode," "Movie Mode," "Sleep Mode," and "Guest Mode"). When the user presses a first-category button again, it no longer controls the lights but triggers the corresponding smart scene. For example, pressing the "Away Mode" button will turn off all lights, close the curtains, and turn off the air conditioner through the linkage control platform. Touching the second-category button again switches back to the first operating mode.

[0128] As can be seen, this solution allows a limited number of physical buttons to achieve twice the functionality, making it particularly suitable for users who want to expand their control capabilities without increasing the number of buttons. Furthermore, because the screen display changes with mode switching, users always clearly understand the function of each button, avoiding confusion.

[0129] In some embodiments, the smart wall switch further includes an indicator light (e.g., the light-emitting element 44 described in later embodiments) for identifying the second type of button. Specifically, the second type of button is a touch button, which has no physical displacement and may be difficult for users to locate in a dark environment. Therefore, an indicator light is provided next to or below the touch button. When the smart wall switch is powered on, the indicator light is constantly lit or dimly lit, indicating the location of the touch button. The indicator light uses an LED.

[0130] Furthermore, the processor is also configured to be able to:

[0131] Receive screen brightness configuration command;

[0132] In response to the screen brightness configuration command, adjust the display brightness of the screen;

[0133] The brightness of the indicator light is adjusted synchronously according to the display brightness of the screen.

[0134] Specifically, users can adjust the screen brightness of the smart wall switch (e.g., from 1% to 100%) via a mobile app. Upon receiving the brightness configuration command, the processor adjusts the screen brightness (e.g., the backlight of an LCD or the display brightness of an OLED) to the specified value. Simultaneously, based on this brightness value, it adjusts the brightness of the indicator lights (e.g., using PWM). For example, increasing the screen brightness causes the indicator lights to brighten, and decreasing the screen brightness causes them to dim.

[0135] Furthermore, this solution can maintain consistent brightness between the screen and indicator lights, resulting in a visually harmonious appearance.

[0136] Furthermore, the processor synchronously adjusts the brightness of the indicator light, specifically for:

[0137] According to the preset correspondence, the brightness of the indicator light is adjusted to match the display brightness of the screen.

[0138] Specifically, "matching" does not require that the brightness values ​​of the two be absolutely equal, but rather that they be coordinated according to a certain mapping relationship so that the human eye perceives them as harmonious.

[0139] For example, the preset correspondence includes: the display brightness of the screen and the brightness of the indicator light correspond to the same brightness level.

[0140] For example, the display brightness of the screen and the brightness of the indicator light both have multiple brightness levels, and the two correspond to each other at the same brightness level.

[0141] In a further example, the multiple brightness levels include three brightness levels. For instance, the screen brightness is divided into three levels: low, medium, and high, and the indicator light brightness is also divided into three levels: low, medium, and high. When the user selects "medium" brightness on the app, the processor automatically sets the indicator light brightness to "medium" as well. At this time, the screen brightness is about 50%, and the indicator light brightness is also about 50%, making them appear to have the same brightness.

[0142] For example, the screen brightness linearly increases from 0 to 255, and the indicator light brightness adjusts in the same linear proportion, with the two corresponding in brightness levels. Specifically, the smart wall switch screen supports stepless brightness adjustment (e.g., from 0 to 100%), and the processor can directly use the screen brightness percentage as the indicator light brightness percentage for adjustment. That is, when the screen brightness is 80%, the indicator light also lights up with an 80% PWM duty cycle, achieving precise synchronization.

[0143] In some embodiments, such as Figure 6 As shown, the smart wall switch also includes a display cover that covers the second type of buttons and the screen.

[0144] The display cover has a light-transmitting mark (such as indicator pattern 511 in a later embodiment) at the position corresponding to the second type of button, and a light-transmitting window (such as display area 52 in a later embodiment) at the position corresponding to the screen.

[0145] The indicator light is located below the light-transmitting mark and is used to illuminate the light-transmitting mark to indicate the position of the second type of button.

[0146] Specifically, in the area corresponding to the touch button (such as touch area 51 in a later embodiment), a light-transmitting mark, such as a small dot or a function icon (such as a spiral arrow), is created on the surface of the display cover using laser engraving, screen printing, or etching. This light-transmitting mark is light-transmitting, while other areas are opaque or semi-transparent. An indicator light (LED) is mounted on the circuit board below this light-transmitting mark. When the indicator light is on, light passes through the light-transmitting mark, and the user can see a glowing pattern, thus knowing that there is a touch button. A light-transmitting window (usually a transparent area) is opened at the corresponding location on the screen, through which the screen displays content.

[0147] Furthermore, the area where the screen and the second type of buttons are located appears as a single, flat display cover without any protruding buttons, resulting in a very strong visual integration. At the same time, the backlighting indicates the location of the touch buttons, balancing aesthetics and practicality.

[0148] Furthermore, such as Figure 6 As shown, the screen includes a first display screen and a second display screen;

[0149] The first type of buttons includes multiple buttons, which are respectively located in the upper and lower areas of the display cover.

[0150] The second type of button and the light-transmitting mark are positioned between the first display screen and the second display screen.

[0151] Specifically, the smart wall switch provided in this embodiment is a dual-screen smart wall switch, with a screen on each of the left and right sides of the front, and the middle area reserved for touch buttons and a light-transmitting indicator. The first type of buttons (mechanical buttons) are distributed on the upper and lower sides of the display cover: for example, two mechanical buttons on the top and two on the bottom, for a total of four. The touch buttons are located between the left and right screens, and the light-transmitting indicator is also located in the middle.

[0152] like Figure 6 As shown, the translucent indicator adopts the shape of a paperclip (a rounded square with a hollow center). When the user clicks on the location of the paperclip, the touch sensing circuit generates a sensor switch signal. After the processor detects this, it simultaneously switches the content displayed on the left and right screens. For example, if the two screens were originally displaying the button names of each mechanical button in the first working mode, clicking the paperclip will cause both screens to switch to displaying the scene names corresponding to each mechanical button in the second working mode.

[0153] With this design, the front layout of the switch is very clear: the screens on both sides are responsible for display, the touch button in the middle is responsible for mode switching, the mechanical buttons on the top and bottom are responsible for specific control, and the display cover integrates the touch button and the screen into a whole.

[0154] In some embodiments, the front of the smart wall switch adopts a "three-part design," dividing the front of the switch panel into three parts: upper, middle, and lower. The width of the three parts is basically the same, with the display cover occupying one part and the buttons occupying the other two parts. The phrase "basically the same width" can be understood as a width difference of less than 3mm.

[0155] For example, such as Figure 7 and Figure 10 The diagram shows a row installation of a single-button smart wall switch, a double-button smart wall switch, and a triple-button smart wall switch. The display cover is located above the first type of button (mechanical button). The longitudinal width of the display cover is H1, and the longitudinal width of the mechanical button is H2. The difference between H2 and twice H1 is less than 3mm. In one embodiment, H2 = 2 × H1.

[0156] like Figure 8 and Figure 11The image shows a front view of a four-button smart wall switch. The display cover is located in the center of the switch panel. Two mechanical buttons are located on the upper side of the display cover, and two more are located on the lower side. The vertical width of the display cover is H4, the vertical width of the mechanical buttons on the upper side of the display cover is H3, and the vertical width of the mechanical buttons on the lower side of the display cover is H5. The difference between H3, H4, and H5 is less than 3mm. In one embodiment, H3 = H4 = H5.

[0157] like Figure 9 The diagram shows a row installation of single-button, double-button, triple-button, and quadruple-button smart wall switches. The advantage of the "tripartite design" is that the height of the dividing line between the display cover and the buttons is consistent for each smart wall switch. Furthermore, the display cover is black, and the first type of buttons are white or gray, so that when multiple smart wall switches are installed in a row, the display covers of different smart wall switches are arranged in a staggered pattern.

[0158] Furthermore, the back of the display cover is covered with a first light-shielding layer and a second light-shielding layer. The first light-shielding layer covers a first area of ​​the display cover, which corresponds to the light-transmitting window of the screen; the second light-shielding layer covers a second area of ​​the display cover, which is defined as the area outside the first area. The first light-shielding layer is a black transparent coating, and the second light-shielding layer is a black opaque coating. Therefore, when a user observes the smart wall switch from the outside, it is difficult to see the boundary of the display area, and the display cover visually presents a unified black effect. The black transparent coating can be understood as a coating similar to sunglasses; when there is a light source behind the display cover, the light can be seen through the black transparent coating, and when there is no light source behind the display cover, it is difficult to see the structure behind the display cover.

[0159] In some implementations, such as Figure 7 As shown, the number of screens for single-button smart wall switches, double-button smart wall switches, and triple-button smart wall switches is the same as the number of first-type buttons. Each screen is set on the upper side of each first-type button, and the screen is used to display the button identification information of the corresponding first-type button.

[0160] In some implementations, such as Figure 8 As shown, the four-button smart wall switch has two screens arranged horizontally. The left screen displays the button identification information for the two left-side Type I buttons, and the right screen displays the button identification information for the two right-side Type I buttons. Furthermore, each screen displays two lines of text: the first line indicates the button information for the upper Type I button, and the second line indicates the button information for the lower Type I button.

[0161] exist Figure 7 and Figure 8 In one embodiment, the screen is a monochrome display.

[0162] In some embodiments, the screen projects a first projection pattern onto the display cover plate, and the distance between the outer contour of the first projection pattern and the outer contour of the display cover plate is greater than 2.5 mm. That is, the display cover plate has a border with a width greater than 2.5 mm around the screen, so that an insulating protective layer with a width greater than 2.5 mm is formed around the screen.

[0163] In some implementations, such as Figure 10 and Figure 11 As shown, the single-button, double-button, triple-button, and quad-button smart wall switches all use a single screen. The screen's size is adapted to the display cover, allowing it to occupy the majority of the cover's area and achieve a large-screen display effect. The button identification information for each of the first-type buttons is integrated and displayed on this single screen.

[0164] like Figure 12 As shown in one embodiment of this disclosure, the smart wall switch is capable of communicating with external devices. Specifically, the processor is also used to communicate with external devices, receive control commands, or report status information.

[0165] In this embodiment of the disclosure, the processor is configured to perform at least one of the following operations:

[0166] The screen displays the dynamic change process of at least one display object, and monitors whether the display object reaches a preset state during the dynamic change process. When the preset state is reached, the corresponding state information is sent to the external device so that the external device executes the corresponding control logic according to the pre-configured linkage rules.

[0167] The device receives control commands from the external device and controls the displayed object on the screen to begin the dynamic change process according to the control commands; wherein the control commands are generated by the external device based on the received status information and in accordance with pre-configured linkage rules.

[0168] Specifically, the display object refers to a visual element presented on the screen, and its form is not limited to static graphics; it can be a dynamically changing visual element. For example, the display object includes graphics, icons, or animated characters. Figure 13 As shown, the displayed object can be an icon of a small airplane. In other examples, the displayed object can also be a dynamic icon representing different device states (such as a fan blade spinning icon, a light bulb brightness indicator icon, etc.).

[0169] The dynamic change process refers to the visual manifestation of a displayed object changing its shape, position, color, size, and other attributes on the screen over time. For example, the dynamic change process includes the displayed object moving along a preset path on the screen; or, at least one of scaling, rotation, or color change of the displayed object. Figure 13 As shown, the displayed object can be an airplane icon that moves at a constant speed from the left side of the screen to the right side, a pulse effect that grows larger and then shrinks back, or a loading icon that rotates 360 degrees.

[0170] In this embodiment, the processor may only perform reporting operations, i.e., act solely as a trigger. Specifically, the smart wall switch displays a dynamic change process on the screen, and the processor monitors the position or playback progress of the displayed object in real time. When the processor detects that the displayed object has reached a preset state (e.g., moved to the edge of the screen, or the video has reached its end frame), it sends this state information to an external device via a communication module. The smart wall switch itself does not wait to receive control commands.

[0171] In this embodiment, the processor may only receive control commands, acting solely as a controlled terminal. Specifically, the smart wall switch may normally be in standby mode or displaying static content, without actively reporting status information. When the processor receives a control command from an external device via the communication module, it parses the command and then controls the displayed object on the screen to begin a dynamic change process. The smart wall switch itself does not report its status externally; it only passively responds to external commands.

[0172] In this embodiment, the processor can also simultaneously perform both reporting and receiving functions. That is, a smart wall switch can both monitor its own dynamic changes and report status information, and also receive control commands from external devices and execute the corresponding dynamic changes. This allows the smart wall switch to act as a relay in the linkage process; when it is triggered as a controlled end to begin executing a dynamic change process, after its own dynamic change process ends, it will again act as a trigger end to report status information, thereby triggering the next smart wall switch.

[0173] Furthermore, when multiple smart wall switches are arranged side by side, the above solution can achieve a continuous dynamic display effect across devices. That is, multiple smart wall switches interact with the external device through their respective display states, enabling the transfer of display states between different smart wall switches, thereby forming a continuous display effect across devices.

[0174] In some embodiments, the external device includes another smart wall switch or control platform, the control platform including a cloud server and / or a gateway.

[0175] The linkage rule includes at least one condition-action pair. The condition-action pair is triggered by the status information reported by a smart wall switch and executed by controlling the display object of this smart wall switch or another smart wall switch to start a dynamic change process. The external device determines the matching condition-action pair based on the received status information and issues control commands to the corresponding smart wall switch according to the execution actions defined by the matching condition-action pair.

[0176] In this embodiment, the control platform can be understood as a device or system capable of receiving status information reported by the smart wall switch, generating control commands according to user-preset linkage rules, and sending the control commands to the smart wall switch. The control platform can be a remote server deployed in the cloud, a local gateway, smart home hub, or edge computing node deployed in a home LAN, or a hybrid architecture system where the cloud and local systems work together. Regardless of the specific implementation of the control platform, as long as it performs the functions of "receiving external events, matching linkage rules, and issuing control commands," it falls within the protection scope of this disclosure.

[0177] Specifically, if the external device includes another smart wall switch, the linkage rules can be pre-stored locally on that other smart wall switch. For example, smart wall switch B stores the linkage rule: "When receiving status information from smart wall switch A, control its own displayed object to move from the left." When smart wall switch A detects that the displayed object has reached the preset state, it directly sends the status information to smart wall switch B (through a local area network point-to-point connection, such as Bluetooth, ZigBee, etc.). After receiving the status information, smart wall switch B parses the status information, matches it with the locally stored linkage rules, and controls its own displayed object to begin the dynamic change process according to the matching rules. This solution does not require cloud or gateway involvement, resulting in shorter communication links and lower response latency.

[0178] If the external device includes the control platform, the linkage rules are pre-stored in the control platform. Users can log in to the control platform via a terminal device (such as a mobile app) to create or modify linkage rules. For example, a user can define "when the dynamic change process of the displayed object of smart wall switch A ends, the screen of smart wall switch B will start displaying the dynamic change process of the displayed object." This rule is stored in the database of the control platform in the form of a condition-action pair.

[0179] When smart wall switch A detects that the displayed object has reached a preset state (such as the end of a dynamic change process), it sends the status information to the control platform. Upon receiving the status information, the control platform parses it and queries the database for a matching condition-action pair. If a match is found, a control command is generated based on the action defined in the matching condition-action pair. This control command includes the target smart wall switch's device identifier (such as device ID) and the action type (controlling the screen to begin the dynamic change process following the object). The control platform then sends this control command to the target smart wall switch B. Upon receiving the control command, smart wall switch B controls the displayed object on its screen to begin the dynamic change process.

[0180] Furthermore, let's take three smart wall switches, A, B, and C, arranged side by side as an example:

[0181] Users pre-configure linkage rules 1-3 on a cloud server (an optional method for external devices), where:

[0182] Rule 1: When the displayed object of smart wall switch A reaches the second end of the screen, control smart wall switch B to start moving the displayed object from the first end of the screen;

[0183] Rule 2: When the displayed object of smart wall switch B reaches the second end of the screen, control the displayed object of smart wall switch C to start moving from the first end of the screen;

[0184] Rule 3: When the displayed object of smart wall switch C reaches the second end of the screen, the displayed object of smart wall switch A shall start moving from the first end of the screen.

[0185] In actual operation, such as Figure 13 As shown, the displayed object of smart wall switch A moves from the first end of the screen to the second end, and reports its status information to the cloud server upon reaching the second end. The cloud server matches linkage rule 1 and sends a control command to smart wall switch B. After receiving the command, smart wall switch B's displayed object moves from the first end to the second end, and reports its status information to the cloud server upon reaching the second end. An external device matches linkage rule 2 and sends a control command to smart wall switch C. After receiving the control command, smart wall switch C's displayed object moves from the first end to the second end, and reports its status information to the cloud server upon reaching the second end. The cloud server matches linkage rule 3 and sends a control command to smart wall switch A. Smart wall switch A receives the control command and resumes its movement. This cycle repeats, forming a relay effect from smart wall switch A to B, then to C, and back to A. The user visually sees a displayed object (e.g., Figure 13The small airplane flies in from the left side of the screen of smart wall switch A, passes through the screens of the three smart wall switches (A, B, C), and finally flies out from the right side of smart wall switch C, and continues to cycle.

[0186] Furthermore, in scenarios where multiple switches are arranged side by side, a coherent and interesting cross-device dynamic display effect is formed.

[0187] In some embodiments, the dynamic change process is achieved by playing media data, and the preset state includes the media data playback progress reaching a preset progress.

[0188] The media data can be understood as digital content capable of presenting dynamic visual effects through decoding and rendering. For example, media data includes, but is not limited to, video files (such as MP4 and AVI formats), GIF animations, and sequential frame animations (such as a series of PNG images played in sequence). The media data can be pre-stored locally on the smart wall switch. The processor converts the media data into screen-displayable image frames using a decoder and displays them frame by frame in chronological order, thereby presenting a continuous dynamic effect on the screen.

[0189] Furthermore, the media data includes video data; the preset progress includes the playback progress of the video data reaching a preset frame (e.g., an intermediate frame).

[0190] For example, the preset frame includes a start frame and / or an end frame.

[0191] In a further example, the screen is a rectangular screen, and the dynamic change process includes the display object moving along a preset path on the screen; the preset path is a straight path, and the display object moves from the first edge of the rectangular screen to the second edge of the rectangular screen; wherein the first edge and the second edge are two opposite edges, the display object is located at the first edge of the rectangular screen in the starting frame of the video data, and the display object is located at the second edge of the rectangular screen in the ending frame of the video data.

[0192] Specifically, the smart wall switch internally stores a short video file containing N frames. While playing the video, the processor records the current frame number in real time. When the initial frame begins playback, the displayed object is located at the first edge of the screen; when the final frame (frame N) is reached, the displayed object is located at the second edge of the screen, opposite the first edge. The processor can report the frame number with a preset progress as status information to an external device. The external device, according to preset linkage rules, sends a control command to another smart wall switch, carrying the information "play the initial frame." Upon receiving the control command, the other smart wall switch begins playing the video from the initial frame.

[0193] For example, the short video file shows a small airplane flying at a constant speed from the left side of the screen to the right side. The video contains N frames. In the first frame (starting frame), the airplane is located at the far left of the screen (e.g., coordinates (0, Y)), and in the Nth frame (ending frame), the airplane is located at the far right of the screen (e.g., coordinates (W, Y), where W is the screen width in pixels). While playing the video, the processor records the current frame number in real time. When the ending frame (the Nth frame) is reached, the processor reports this frame number as status information to an external device. The external device, according to preset rules, sends a control command to another smart wall switch, carrying the information "play the starting frame". After receiving the command, the other smart wall switch starts playing the video from the starting frame, thus visually creating the effect of the airplane flying from the left side of the screen. Figure 14 As shown, another shape and Figure 13 The smart wall switches shown are different types of smart wall switches. These smart wall switches come in single-button, double-button, and triple-button models. When these three types of smart wall switches are arranged side-by-side, they present the following... Figure 14 The layout shown depicts each smart wall switch with a screen. The left smart wall switch reports status information when playing a video to the end frame. The middle smart wall switch, upon receiving a control command, starts playing from the beginning frame and reports status information upon reaching the end frame. The right smart wall switch, upon receiving a control command, starts playing from the beginning frame. This creates a continuous visual effect where a small airplane flies in from the left smart wall switch screen, passes through the middle smart wall switch screen, and flies out from the right smart wall switch screen.

[0194] In some embodiments, the preset state includes the display position of the display object on the screen matching a preset position on the screen.

[0195] Specifically, if the error between the real-time position coordinates of the displayed object on the screen and the preset position coordinates is within an allowable range (e.g., pixel-level matching), or if the boundary of the displayed object touches the preset position, it is determined that the display position of the displayed object on the screen matches the preset position on the screen. The processor maintains the real-time coordinates (X, Y) of the displayed object and compares them with the preset screen coordinates. When certain conditions are met (e.g., X ≤ 0 indicates reaching the left edge, or X ≥ screen width indicates reaching the right edge), it is determined that the preset state has been reached.

[0196] Furthermore, the screen is a rectangular screen, and the preset position includes at least one midpoint pixel position on at least one side of the rectangular screen.

[0197] Specifically, taking a rectangular screen as an example, the coordinates of the top-left corner are (0,0), and the coordinates of the bottom-right corner are (W, H), where W is the number of pixels in the width direction of the screen, and H is the number of pixels in the height direction of the screen. The preset position can be any pixel on the top edge (y-coordinate = 0), bottom edge (y-coordinate = H), left edge (x-coordinate = 0), and right edge (x-coordinate = W) of the screen, preferably the midpoint pixel position of each edge, such as the midpoint of the left edge and the midpoint of the right edge. When the coordinates of a specific anchor point of the displayed object (such as the geometric center point or left boundary of the displayed object) match these midpoint pixel positions, it is considered that the preset state has been reached.

[0198] For example, the dynamic change process includes the display object moving along a preset path on the screen; the preset path is a straight path, and the display object moves from a first pixel position on a first edge of the rectangular screen to a second pixel position on a second edge of the rectangular screen; wherein, the first edge and the second edge are two opposite edges, the first pixel position is the endpoint pixel position of the first edge, and the second pixel position is the endpoint pixel position of the second edge.

[0199] Specifically, the processor updates the coordinates of the displayed object through frame-by-frame refresh or timer interrupts. For example, the initial position of the displayed object is the midpoint of the left edge. Each frame, the horizontal coordinate increases by ΔX until it reaches W (the number of pixels in the screen width direction), at which point the displayed object has reached the midpoint of the right edge. After each frame update, the processor determines the current coordinates of the displayed object. When it detects that the horizontal coordinate is ≥ W, it determines that a preset state has been reached. The processor then reports the coordinate information (such as "Right edge reached") as status information to the external device.

[0200] Using the airplane icon as an example, three smart wall switches are arranged side-by-side, each with a 320×480 pixel screen. The airplane moves in a straight line from the left edge (horizontal coordinate 0) to the right edge (horizontal coordinate 320). When the left smart wall switch A detects that the airplane's horizontal coordinate has reached 320, it reports the status information "the displayed object of smart wall switch A has reached the right edge" to the cloud server. After matching the linkage rules, the cloud server sends a control command to the middle smart wall switch B, which includes "the displayed object on the screen starts moving from the left edge." After receiving the control command, the middle smart wall switch B places the airplane at horizontal coordinate 0 and starts moving; it reports when it moves to horizontal coordinate 320. The cloud server then triggers the right smart wall switch C; the right smart wall switch C reports when it moves to horizontal coordinate 320; the cloud server then triggers the left smart wall switch A again according to the loop rule. This process repeats, creating the effect of a small airplane flying in a loop between the three smart wall switches. Visually, the user sees the small airplane continuously flying in from the leftmost smart wall switch, passing through the three screens, and flying out from the rightmost smart wall switch, in a continuous loop.

[0201] Furthermore, the smart wall switch provided in this disclosure monitors the dynamic changes of the objects displayed on the screen and reports status information when a preset state is reached. This enables external devices to trigger other smart wall switches to perform corresponding dynamic changes according to linkage rules, achieving a continuous dynamic display effect across devices. Multiple smart wall switches arranged side by side can form relay or loop animation effects through this mechanism, greatly enhancing the interactive fun and visual intuitiveness.

[0202] In some embodiments, this disclosure also provides a smart wall switch. This embodiment focuses on the structural scheme of the smart wall switch, and this embodiment can be combined with the above embodiments to form an overall implementation scheme that includes both software and structure.

[0203] Please see Figures 15-35 The intelligent wall switch 100 provided by this invention will be specifically explained. For example, Figure 26 as well as Figures 22-24As shown, the smart wall switch 100 includes a middle shell 3, a first circuit board 4, multiple buttons 1, and a connecting part 2. The first circuit board 4 is disposed on the middle shell 3 and has multiple electronic switches 41. Each button 1 corresponds to a specific electronic switch 41. Each button 1 has a trigger part 131 for directly or indirectly triggering the electronic switch 41. The connecting part 2 connects the buttons 1 into a whole, so that the positional relationship between the buttons 1 is precisely limited by the connecting part 2, thereby ensuring the consistency of the gaps between the buttons 1 and improving the relative positional accuracy between the buttons 1 and the middle shell 3. The electronic switches 41 can be tactile switches, micro switches, detection switches, or other electronic switches 41. In the exemplary embodiment, the electronic switches 41 are tactile switches.

[0204] like Figure 23 and Figure 24 As shown, where Figure 24 This is a partial structural diagram of a button 1 and a connecting part 2. The purpose is to facilitate observation of the structure of button 1. Figure 24 The left button 1 is hidden, and only the right button 1 is shown. Multiple corners of the button 1 away from the connecting part 2 are set as pressing angles 11. Each pressing angle 11 forms a corresponding limiting area 12 on the edge region of the button 1, facing the trigger part 131. The trigger part 131 is located between each pressing angle 11 and the corresponding limiting area 12. When a pressing angle 11 is pressed, the limiting area 12 corresponding to that pressing angle 11 is limited by the middle shell 3 and cannot tilt upwards, making the limiting area 12 the fulcrum for the movement of the button 1, ensuring that the trigger part 131 triggers the electronic switch 41. Unlike the pivotal movement of existing integrated buttons, the button 1 provided in this embodiment moves around each limiting area 12 as a fulcrum. The button 1 can tilt toward each pressed pressing angle 11, greatly improving the flexibility of the button 1 and the pressing feel. Furthermore, each limiting area 12 corresponds to a fulcrum for each pressing angle 11, and each pressing angle 11, trigger part 131, and corresponding limiting area 12 form a lever-like structure, ensuring that pressing each pressing angle 11 can trigger the electronic switch 41, increasing the pressable area of ​​the button 1. This solves the problems in the prior art.

[0205] The corners of button 1 can be understood as the positions where the two edges of button 1 intersect. For example, a rectangular button 1 has four corners, two, three, or all four of which can be pressing corners 11. The number of pressing corners 11 is related to the position of the connecting part 2. For example, when the connecting part 2 is located in the area of ​​one corner of the rectangular button 1, the other three corners of the button 1 can all be used as pressing corners 11. For example, when the connecting part 2 is located in the area of ​​an entire side of the rectangular button 1, the two corners of the button 1 away from that side can all be used as pressing corners 11. For example, when the connecting part 2 is located in the middle of one side of the rectangular button 1 and the connecting part 2 is very narrow, all four corners of the button 1 can be used as pressing corners 11.

[0206] It is worth noting that in this embodiment of the invention, the pressing angle 11 is set at the position of the button 1 away from the connecting part 2, while the pressing angle 11 is not set at the position of the button 1 near the connecting part 2. This avoids the button 1 being accidentally triggered due to the linkage between the buttons when the position near the connecting part 2 is pressed, thus providing conditions for the organic integration of integrated button technology and large-area pressing technology.

[0207] The connection part 2 connects each button 1 into a whole, which can be understood as the connection part 2 and the button 1 being integrally formed or fixedly connected as a whole. The trigger part 131 can directly abut against the electronic switch 41 to directly trigger the electronic switch 41, or it can indirectly trigger the electronic switch 41 by driving other components.

[0208] The number of buttons 1 can be 2, 3, 4 or more. The buttons 1 can be arranged side by side in one direction or in a matrix arrangement with multiple rows and columns.

[0209] The limiting area 12 corresponding to the pressing angle 11 can be understood as, for example, Figure 24 As shown, a straight line is drawn from the pressing angle 11 toward the trigger part 131. The area near the intersection of this straight line and the edge of the button 1 forms the limiting area 12. Each pressing angle 11 forms a corresponding limiting area 12. Figure 24 In the diagram, the limiting region 12 is marked with a dashed box. The limiting region 12 can be understood as a relatively large area, including not only the area that is linearly distributed with the trigger part 131 and the pressing angle 11, but also the area that deviates slightly from the linear distribution. As long as the limiting region 12 forms an approximately linear relationship with the trigger part 131 and the pressing angle 11, it is within the protection scope of this invention.

[0210] In one embodiment, the limiting region 12 is set as a rectangular region with a side length greater than 6 mm and less than 14 mm.

[0211] The limiting region 12 is limited by the middle shell 3 in a manner that can be snap-fit ​​limiting, abutting limiting, or other limiting methods that can prevent the limiting region 12 from tilting upwards. The specific limiting methods are described in detail below.

[0212] Furthermore, such as Figure 22 , Figure 25 , Figure 26 As shown, the middle shell 3 is provided with a reset member, which provides a reset force for the button 1. The button 1 and the first circuit board 4 are disposed on both sides of the middle shell 3. The reset member includes an elastic arm 31, which is disposed between the trigger part 131 and the electronic switch 41. The trigger part 131 is constructed as a trigger post, which abuts against the elastic arm 31, thereby triggering the electronic switch 41 through the elastic arm 31. Specifically, the trigger part 131 abuts against the upper surface of the elastic arm 31, and the lower surface of the elastic arm 31 abuts against the trigger button 411 of the electronic switch 41. The trigger part 131 presses down on the elastic arm 31, causing the elastic arm 31 to undergo downward elastic deformation, thereby pressing the trigger button 411 of the electronic switch 41, thus triggering the electronic switch 41.

[0213] The elastic arm 31 not only provides a reset force for button 1, but also provides a supporting force for button 1, preventing adjacent buttons from being pressed down and causing the electronic switch 41 to be accidentally triggered when one button 1 is pressed. Furthermore, the supporting force of the elastic arm 31 makes the button 1 more resilient to press, preventing it from feeling soft and limp.

[0214] It is worth mentioning that when button 1 is not pressed, the elastic arm 31 is in a pre-compressed state, so that the elastic arm 31 provides elastic support at all times, so that button 1 will not be loose.

[0215] like Figure 25 As shown, the trigger part 131 and the trigger button 411 of the electronic switch 41 respectively abut against different sections of the elastic arm 31. The abutting positions of the two are marked with dashed lines in the figure. As can be seen from the figure, the position of the trigger part 131 and the position of the trigger button 411 are offset in the horizontal direction. When the electronic switch 41 is triggered, the vibration of the electronic switch 41 cannot be directly transmitted longitudinally to the button 1. It must be transmitted laterally through the elastic arm 31 to be transmitted to the button 1. The elastic arm 31 is elastic and can buffer the vibration of the electronic switch 41, thereby improving the pressing feel of the button 1. Even if the electronic switch 41 uses a hard button, its vibration can be effectively buffered.

[0216] In some embodiments, the trigger button 411 of the electronic switch 41 is a rigid button. Although the rigid button produces a stronger vibration when the electronic switch 41 is triggered, the elastic arm 31 provides excellent cushioning, effectively reducing vibration transmission. This allows the electronic switch 41 with the rigid button, in conjunction with the elastic arm 31, to still provide a good tactile feel for button 1. Using a rigid button not only results in a shorter trigger stroke but also better consistency in the trigger stroke. That is, the trigger stroke of electronic switches 41 produced in different batches fluctuates less, which is beneficial for precise control of the button 1's stroke and provides a structural basis for the implementation of ultra-thin panels. The rigid material can be understood as a material that is not easily compressed macroscopically, such as plastic, iron, brass, aluminum alloy, etc. In one embodiment, the electronic switch 41 is a tactile switch, and the rigid button is made of brass.

[0217] The panel of the smart wall switch 100 can be understood as the part located on the outside of the wall when the smart wall switch 100 is installed on the wall.

[0218] Furthermore, since a portion of the travel of button 1 is consumed by the deformation of the elastic arm 31, the effective travel of button 1 is shortened, and there is a risk that button 1 may fail to trigger the electronic switch 41 within its effective travel. Therefore, in this embodiment of the invention, as... Figure 25 As shown, the elastic arm 31 includes a fixed end connected to the middle shell 3. Along the extending direction of the elastic arm 31, the fixed end, the trigger part 131, and the trigger button 411 are sequentially distributed. Thus, the elastic arm 31 forms a lever that requires more effort. The stroke of the trigger part 131 is amplified at the location of the trigger button 411, thereby compensating for the stroke loss caused by the deformation of the elastic arm 31 and ensuring that the button 1 can trigger the electronic switch 41 within its effective stroke.

[0219] Furthermore, such as Figure 25 As shown, the extension direction of the elastic arm 31 is a curved direction.

[0220] In some embodiments, such as Figures 22-24 as well as Figures 34-35 As shown, each button 1 includes a button plate 14 and a button bracket 13. The button bracket 13 is connected to the middle shell 3, and the connecting part 2 connects each button bracket 13 into one unit. The button plate 14 is integrally formed or fixedly connected to the button bracket 13; wherein, in Figures 22-24 In this embodiment, the button panel 14, the button bracket 13, and the connecting part 2 are integrally injection molded from plastic material. Figures 34-35 In this embodiment, the button bracket 13 and the connecting part 2 are integrally injection molded from plastic material, and the button plate 14 is made of glass material, and the button plate 14 is pasted and fixed to the upper surface of the button bracket 13.

[0221] like Figure 24 As shown, the limiting area 12 is located in the area of ​​the button bracket 13 that is diagonally distributed with each of the pressing angles 11. The button bracket 13 is provided with a locking part 132 in the limiting area 12. The locking part 132 is locked with the middle shell 3 to limit the extreme position of the upward movement of the limiting area 12, thereby ensuring that the user can successfully trigger the electronic switch 41 by pressing each pressing angle 11. The area of ​​the button bracket 13 that is diagonally distributed with each pressing angle 11 can be understood as follows: the upper left corner of the button bracket 13 is diagonally distributed with the lower right corner of the button plate 14, the upper right corner of the button bracket 13 is diagonally distributed with the lower left corner of the button plate 14, and the lower left corner of the button bracket 13 is diagonally distributed with the upper right corner of the button plate 14.

[0222] The limiting area 12 can be located exactly at the corner of the button bracket 13, or slightly off the corner of the button bracket 13. The locking part 132 can be located at the center of the limiting area 12, or at the edge of the limiting area 12. The locking part 132 can be a hook, a step, or other structure capable of locking.

[0223] Furthermore, such as Figures 22-24 as well as Figures 34-35 As shown, the button bracket 13 protrudes from the back of the button plate 14.

[0224] Furthermore, such as Figure 20 and Figure 23 As shown, there are four buttons 1, which are distributed at four corners around the connecting part 2. The connecting part 2 is positioned at the center of the four buttons 1, so that each button 1 is connected to the connecting part 2 at only one corner, reducing the linkage between the buttons 1. Furthermore, since each button 1 is connected to the connecting part 2 at only one corner, the three corners of the button 1 furthest from the connecting part 2 are all pressing corners 11, which can all be pressed to trigger the electronic switch 41, thus increasing the pressing area of ​​the button 1.

[0225] It is worth mentioning that, compared to arranging the four buttons 1 along a straight line, which results in the buttons 1 having an elongated shape, the buttons 1 in this embodiment are distributed at the four corners, making the shape of the buttons 1 more square and more suitable for the large area of ​​the buttons 1 to be pressed.

[0226] Furthermore, such as Figure 20 As shown, the four buttons 1 are located at the upper left, upper right, lower left, and lower right corners of the connecting part 2, respectively. Two buttons 1 are arranged side by side at the upper end of the connecting part 2, and the other two buttons 1 are arranged side by side at the lower end of the connecting part 2.

[0227] Furthermore, such as Figure 24 As shown, the button panel 14 is rectangular, including a first pressing angle 111 diagonally distributed with respect to the connecting portion 2, and a second pressing angle 112 and a third pressing angle 113 adjacent to the connecting portion 2. The first pressing angle 111, the second pressing angle 112, the third pressing angle 113, and the connecting portion 2 are distributed in the four corner areas of the button panel 14. The button bracket 13 includes a first limiting area 121 diagonally distributed with respect to the first pressing angle 111, a second limiting area 122 diagonally distributed with respect to the second pressing angle 112, and a third limiting area 123 diagonally distributed with respect to the third pressing angle 113. The trigger portion 131 is located between the first pressing angle 111 and the first limiting area 121, between the second pressing angle 112 and the second limiting area 122, and between the third pressing angle 113 and the third limiting area 123. The first limiting area 121, the second limiting area 122, and the third limiting area 123 have been... Figure 24 The area is marked with a dashed box. It can be understood that the pressing angle 11 includes the first pressing angle 111, the second pressing angle 112, and the third pressing angle 113, and the limiting area 12 includes the first limiting area 121, the second limiting area 122, and the third limiting area 123.

[0228] In some embodiments, such as Figure 23 and Figure 24 As shown, the area of ​​the button bracket 13 is smaller than the area of ​​the button plate 14, and the button bracket 13 is arranged in a region of the button plate 14 near the connecting part 2. The smaller area of ​​the button bracket 13 allows it to sink into the first recess 38 of the middle shell 3, which is beneficial for achieving an ultra-thin panel. The arrangement of the button bracket 13 in the region of the button plate 14 near the connecting part 2 allows the button brackets 13 of each button 1 to be connected as a single unit by the connecting part 2.

[0229] In some embodiments, such as Figure 23 As shown, the area of ​​the button plate 14 near the connecting part 2 cannot be pressed to avoid the electronic switch 41 being accidentally triggered due to the linkage between the buttons 1; correspondingly, the corners of the button bracket 13 that are diagonally distributed with the connecting part 2 are not provided with the snap-fit ​​part 132, thereby simplifying the structure of the button bracket 13 and the middle shell 3, so that the button bracket 13 can sink into the first recess 38 of the middle shell 3.

[0230] In other embodiments, although the area of ​​the keypad 14 near the connecting portion 2 cannot be pressed, the corners of the keypad bracket 13 that are diagonally distributed with respect to the connecting portion 2 are still provided with snap-fit ​​portions 132.

[0231] In some embodiments, such as Figures 21-23 As shown, the connecting part 2 is supported by the middle shell 3. The area of ​​the button bracket 13 near the connecting part 2 is set as a support area 134. The middle shell 3 is provided with a support part 32 at a corresponding position of the support area 134. The support part 32 is used to support the support area 134 so that the area of ​​the button plate 14 near the connecting part 2 cannot be pressed. The support area 134 can be a small area or a large area. In the exemplary embodiment, the support area 134 is already... Figure 23 The text is marked with a dashed box. Further, such as... Figure 21 As shown, the support portion 32 is constructed as a support protrusion, and there are four support protrusions, which respectively abut against the support area 134.

[0232] In some embodiments, such as Figure 22 and Figure 23 As shown, the latching part 132 includes a button latch 1321, and the middle shell 3 is provided with a latching position 33 at the corresponding position of the button latch 1321. The button latch 1321 is latched into the latching position 33, and the button latch 1321 can move downward in response to the button 1 being pressed.

[0233] Furthermore, the latching portion 132 also includes a button latch 1322, which is disposed in the area of ​​the button bracket 13 near the connecting portion 2. The middle shell 3 has a latching position 33 corresponding to the button latch 1322, and the button latch 1322 latches into the latching position 33. Since the area of ​​the button plate 14 near the connecting portion 2 cannot be pressed, the button latch 1322 cannot move towards the middle shell 3. Figure 23 As shown, there are two button clips 1322, located at the upper and lower ends of the connecting part 2 respectively. The two buttons 1 at the upper end of the connecting part 2 share one button clip 1322, and the two buttons 1 at the lower end of the connecting part 2 share another button clip 1322.

[0234] Furthermore, such as Figure 22 and Figure 23 As shown, the latching part 132 further includes a latching plate 1323. The middle shell 3 has a latching position 33 at a corresponding position of the latching plate 1323. The latching plate 1323 latches into the latching position 33, and the latching plate 1323 can move downward in response to the button 1 being pressed. The latching plate 1323 is thinner, making it less likely to interfere with the first circuit board 4 when moving downward. Furthermore, the latching plate 1323 occupies less thickness of the panel, which is beneficial for achieving an ultra-thin panel.

[0235] Furthermore, such as Figure 27 and Figure 31As shown, the first circuit board 4 is disposed on the side of the middle shell 3 opposite to the button 1. The first circuit board 4 has a relief portion 42 at the position corresponding to the button hook 1321. The relief portion 42 is used to avoid the button hook 1321. Further, the relief portion 42 is constructed as a groove formed on the edge of the first circuit board 4, and the bottom of the button hook 1321 is located inside the relief portion 42.

[0236] Furthermore, such as Figure 27 As shown, the first circuit board 4 has an avoidance part 42 at the position corresponding to the button buckle 1322. The avoidance part 42 is used to avoid interference between the first circuit board 4 and the button buckle 1322. Furthermore, the avoidance part 42 corresponding to the button buckle 1322 is constructed as an opening.

[0237] like Figure 15 As shown, the middle shell 3 is covered by a display cover plate 5. A screen 6 is provided in the area covered by the display cover plate 5. The display content of the screen 6 is displayed to the outside through the display cover plate 5. The display cover plate 5 is long and rectangular. The display cover plate 5 is arranged horizontally. Two buttons 1 are located on one side of the display cover plate 5, and two other buttons 1 are located on the other side of the display cover plate 5. The display cover plate 5 and the buttons 1 are arranged side by side.

[0238] like Figure 24 As shown, the button hook 1321 is located at the end of the button bracket 13 opposite to the display cover 5, and in a corner area adjacent to the connecting part 2. The latching plate 1323 is located at the end of the button bracket 13 near the display cover 5, and in a corner area adjacent to the connecting part 2. The button latch 1322 is located at a corner of the button bracket 13 near the connecting part 2.

[0239] In some embodiments, such as Figures 15-19 As shown, the display cover 5 and the four buttons 1 are arranged side by side. The display cover 5 covers the connecting part 2, and the connecting part 2 is clamped and fixed by the display cover 5 and the middle shell 3. The fixed position of the connecting part 2 prevents the buttons 1 from becoming loose due to movement between the connecting part 2 and the buttons 1, and also ensures a more accurate positional relationship between the buttons 1 and the middle shell 3, guaranteeing a consistent gap width between each button 1 and the display cover 5.

[0240] It is worth mentioning that the connecting part 2 is clamped and fixed by the display cover plate 5 and the middle shell 3, eliminating the need for an additional fixing structure for fixing the connecting part 2, making the structure more compact and conducive to achieving an ultra-thin panel; at the same time, the assembly efficiency is improved.

[0241] Furthermore, such as Figure 15 and Figure 16As shown, four buttons 1 are arranged in pairs on both sides of the display cover 5. There are two screens 6, and the connecting part 2 passes between the two screens 6. Each screen 6 displays the button information of two buttons 1, thus saving the number of screens 6, making the structure more compact, and leaving more space for the buttons 1 to ensure their area. The display cover 5 is a horizontally arranged strip shape, with two buttons 1 located on the upper side of the display cover 5 and the other two buttons 1 located on the lower side. The two screens 6 are arranged left and right. The left screen 6 displays two lines of text or patterns to indicate the functions of the upper left and lower left buttons 1; the right screen 6 displays two lines of text or patterns to indicate the functions of the upper right and lower right buttons 1.

[0242] Existing smart wall switches with integrated buttons typically arrange the buttons in one direction and connect them side by side, resulting in significant inter-button linkage and poor button flexibility.

[0243] To address the above problems, in some embodiments, such as Figures 15-16 As shown, the smart wall switch 100 includes a middle shell 3, a screen 6, a display cover 5, and multiple buttons 1. The screen 6 is disposed on the middle shell 3. The display cover 5 covers the middle shell 3, and the screen 6 is located within the coverage area of ​​the display cover 5. The display content of the screen 6 is displayed externally through the display cover 5. The buttons 1 are disposed on the middle shell 3, and the buttons 1 are arranged side by side with the display cover 5. The connecting part 2 connects the multiple buttons 1 into a whole. The connecting part 2 is disposed on the side of the buttons 1 facing the display cover 5. The connecting part 2 is covered by the display cover 5 and is clamped by the display cover 5 and the middle shell 3.

[0244] In this embodiment of the invention, the connecting part 2 is disposed on the side of the button 1 facing the display cover plate 5, which can reduce the linkage between the buttons 1 and improve the flexibility of the buttons 1. Furthermore, the connecting part 2 is clamped by the display cover plate 5 and the middle shell 3, eliminating the need for an additional fixing structure for fixing the connecting part 2, making the structure more compact and facilitating the realization of an ultra-thin panel; at the same time, assembly efficiency is improved.

[0245] Existing smart wall switches with screens and buttons typically display the functions of the corresponding buttons on the screen. The screen display and button functions can only be changed via a mobile app, limiting the number of functions the switch can control. When the switch needs to control a large number of lights or multiple scene modes, the number of buttons may be insufficient. If the number of buttons is insufficient, a smart wall switch with more buttons can be used, but most smart wall switches on the market are single, double, triple, or four-button switches; more than four buttons can cause inconvenience. If even a four-button smart wall switch is insufficient, a new smart wall switch needs to be added to achieve the desired functionality. Adding a new smart wall switch requires a series of procedures, including wall groove cutting, installation of a junction box, cement drying, wall repair, and wiring, which are beyond the capabilities of ordinary users.

[0246] To solve the above problems, in the embodiments of the present invention, such as Figure 15 As shown, the display cover 5 is provided with display areas 52 corresponding to the screen 6 one by one, and the display content of the screen 6 is displayed to the outside through the display areas 52; the screen 6 is electrically connected to the first circuit board 4, and the first circuit board 4 is provided with electronic switches 41 at the corresponding positions of each button 1, and the button 1 can be pressed to trigger the corresponding electronic switch 41; the first circuit board 4 is provided with a touch component 43, the touch component 43 is located within the coverage area of ​​the display cover 5, and the display cover 5 forms a touch area 51 at the corresponding position of the touch component 43.

[0247] In actual use, the function of button 1 can be switched in response to the touch area 51 being touched, so that one button 1 can control at least two functions, thus expanding the number of functions that the smart wall switch 100 can control, and meeting the usage needs without adding new switches.

[0248] Furthermore, the functions controlled by each button 1 can be switched in response to a single touch operation of the touch component 43. That is, every time the user touches the touch area 51, the functions corresponding to all buttons 1 will be switched, thereby increasing the number of controllable functions of the smart wall switch 100 by a factor of two.

[0249] It is worth mentioning that placing the touch area 51 on the display cover 5 can prevent the touch area 51 from being touched when pressing the button 1.

[0250] The touch area 51 and the display area 52 are already present. Figure 15 The area is marked with a dashed box. The touch component 43 is capable of sensing touch operations on the touch area 51.

[0251] In some embodiments, the screen 6 is used to display the button information of the button 1. The screen 6 can switch the button information of the button 1 in response to the touch operation of the touch component 43, and the function controlled by the button 1 switches synchronously with the button information.

[0252] Furthermore, the default function of each button 1 is to control the on / off state of the corresponding relay. When the touch component 43 is touched, the function of each button 1 is switched to transmit wireless signals, and the smart wall switch 100 transmits wireless signals in response to the button 1 being pressed.

[0253] Furthermore, when the touch component 43 is touched, the function of each button 1 is switched from controlling the on / off state of the relay to controlling the scene mode.

[0254] In some embodiments, the number of touch areas 51 is one, and in other embodiments, the number of touch areas 51 is multiple.

[0255] In some embodiments, the touch area 51 is disposed on the left and right sides of the display area 52; in some embodiments, the touch area 51 is disposed between the display areas 52; in some embodiments, the touch area 51 is disposed on the lower side of the display area 52; and in some embodiments, the touch area 51 is disposed on the upper side of the display area 52.

[0256] In some embodiments, the number of screens 6 is multiple, and the corresponding number of display areas 52 is multiple. The multiple display areas 52 are arranged along a first direction, and the touch area 51 is located between two adjacent display areas 52. Specifically, when there are two buttons 1, there are two corresponding display areas 52. Both buttons 1 and display areas 52 are arranged along the first direction, and the touch area 51 is located between two display areas 52, with the touch area 51 positioned in the middle of the display cover 5. When there are three buttons 1, there are three corresponding display areas 52. Both buttons 1 and display areas 52 are arranged along the first direction, and there are two touch areas 51. The touch area 51 is respectively positioned between each pair of the three display areas 52. Figures 15-16 As shown, when there are four buttons 1, there are two display areas 52 and one touch area 51. The touch area 51 is located between the two display areas 52 and in the middle of the display cover 5.

[0257] In some embodiments, such as Figures 15-16As shown, there are multiple buttons 1, two screens 6, two display areas 52, and at least one touch area 51, which is located between the two display areas 52. The phrase "at least one touch area 51" can be understood as meaning that the number of touch areas 51 is one or more. When there is only one touch area 51, it is located between the two display areas 52; when there are multiple touch areas 51, all of them are located between the two display areas 52.

[0258] Furthermore, the first direction is horizontal, the two display areas 52 are arranged horizontally, and the horizontal width of the display cover 5 is greater than the vertical width.

[0259] Furthermore, such as Figures 15-16 As shown, there are four buttons 1, which are distributed at the four corners and in pairs on the upper and lower sides of the display cover 5; the two screens 6 display the button information of the four buttons 1 respectively.

[0260] Furthermore, such as Figures 15-16 As shown, the display cover 5 is horizontally disposed across the middle shell 3. There is one touch area 51, located in the center of the display cover 5. Two screens 6 are located on the left and right sides of the touch area 51, respectively. The left screen 6 corresponds to the two left buttons 1, and the right screen 6 corresponds to the two right buttons 1. The horizontal displacement can be understood as the left and right ends of the display cover 5 being flush with the left and right sides of the middle shell 3. The correspondence between the screens 6 and the buttons 1 can be understood as the left screen 6 and the two left buttons 1 being distributed in approximately a straight line vertically, and the right screen 6 and the two right buttons 1 being distributed in approximately a straight line vertically.

[0261] In other embodiments (not shown in the figures), there is one screen 6, one display area 52, and multiple buttons 1. The screen 6 displays button information for multiple buttons 1. There are multiple touch areas 51 located on both sides of the display area 52. In this embodiment, instead of multiple small screens 6, a single screen 6 is used, which is larger and displays button information for each button 1. The display area 52 is located in the middle of the display cover 5. Touch areas 51 are provided on both sides of the screen 6. The touch areas 51 can be located on the left and right sides or the top and bottom sides of the screen 6. The functions corresponding to the two touch areas 51 are set to control the left and right or the top and bottom pages of the displayed content. The screen 6 has multiple pages of button information preset. The two touch areas 51 are used to switch between pages of button information. At the same time, the function controlled by the button 1 switches synchronously with the button information. Based on this, the number of controllable functions of the smart wall switch 100 is multiplied.

[0262] In some embodiments, such as Figure 15 and Figure 16 As shown, the touch area 51 is provided with an indicator pattern 511, and the first circuit board 4 is provided with a light-emitting element 44 at a position corresponding to the indicator pattern 511. The indicator pattern 511 is capable of transmitting light from the light-emitting element 44. The indicator pattern 511 is used to indicate the touch area 51. The indicator pattern 511 can be understood as a light-transmitting pattern, and the light-emitting element 44 is preferably an LED. Further, the light-emitting element 44 is positioned directly opposite the indicator pattern 511.

[0263] Furthermore, such as Figure 17 As shown, a light-diffusing sheet 57 is provided on the back of the display cover 5 at the position corresponding to the indicator pattern 511. The light-diffusing sheet 57 is attached to the upper surface of the conductive foam 432. When the display cover 5 covers the middle shell 3, the light-diffusing sheet 57 is sandwiched between the conductive foam 432 and the display cover 5. The light emitted by the light-emitting element 44 is diffused by the light-diffusing sheet 57 and then passes through the indicator pattern 511. Further, the light-diffusing sheet 57 is made of white plastic sheet.

[0264] Furthermore, such as Figure 18 To display the back view of the cover plate 5, the back of the display cover plate 5 is covered with a first coating 551, which is a black opaque coating. The first coating 551 is hollowed out at the corresponding position of the indicator pattern 511 to form the indicator pattern 511. The area of ​​the touch area 51 except for the second coating 552 is covered by the first coating 551, so that the light from the light-emitting element 44 can only pass through the second coating 552.

[0265] The light-emitting element 44 can switch between a light-emitting state and a non-light-emitting state. Visible light with a wavelength of 550nm has a transmittance of greater than 5% and less than 35% through the indicator pattern 511. When the light-emitting element 44 is not emitting light, the indicator pattern 511 appears black, consistent with the color of other areas of the display cover 5, and is visually hidden. The indicator pattern 511 can only be seen by the user when the light-emitting element 44 is emitting light. When the user does not need the touch function, the touch function can be turned off, and the light-emitting element 44 can also be turned off; the indicator pattern 511 will not be displayed, and the display cover 5 will present a uniform black effect. In an exemplary embodiment, the transmittance of the indicator pattern 511 is 15% to better conceal the indicator pattern 511.

[0266] Furthermore, the back of the display cover 5 is covered with a second coating 552 on the indicator pattern 511. The second coating 552 is a black transparent coating, which enables the light transmittance of the indicator pattern 511 to reach the target value. The black transparent coating is similar to the coating on sunglasses; although black, it allows light to pass through.

[0267] Furthermore, the transmittance of visible light with a wavelength of 550nm through the display area 52 is greater than 5% and less than 35%. When the screen 6 is off, the display area 52 appears black to the outside, consistent with the color of other areas of the display cover 5. The display area 52 is visually hidden, and the display cover 5 presents a unified black effect.

[0268] In some embodiments, the brightness of the indicator pattern 511 that transmits light to the outside is set to L1, and the display brightness of the display area 52 is set to L2. This satisfies the relationship: |L1-L2|≤0.2*L2, thus ensuring that the brightness of the indicator pattern 511 that transmits light to the outside is approximately the same as the display brightness of the display area 52. During the design process, researchers use a brightness detector to measure the brightness of the indicator pattern 511 that transmits light to the outside, then adjust the brightness of the screen 6 based on the measurement results. They also use a brightness detector to measure the display brightness of the display area 52. After multiple adjustments to the screen 6 brightness, the final display brightness is made consistent with the brightness of the indicator pattern 511 that transmits light to the outside.

[0269] Furthermore, such as Figure 16As shown, a distance detection module is provided within the area covered by the display cover 5. The light-emitting element 44 emits light in response to the triggering of the distance detection module. During use, when the user is located far from the smart wall switch 100, the distance detection module is not triggered, the light-emitting element 44 does not emit light, and the indicator pattern 511 is displayed as black. The indicator pattern 511 visually blends into the display cover 5, achieving a one-piece black effect for the display cover 5. When the user is located near the front of the smart wall switch 100, the distance detection module is triggered, the light-emitting element 44 is lit, and the light from the light-emitting element 44 shines through the indicator pattern 511, making the indicator pattern 511 visible to the user for touch control.

[0270] Furthermore, the distance detection module includes an infrared emitting unit 451 and an infrared receiving unit 452. The infrared emitting unit 451 is used to emit infrared light, which passes through the display cover 5 and is emitted outward. The infrared light is reflected by external objects and partially returns to the infrared receiving unit 452. When the infrared light received by the infrared receiving unit 452 is greater than a threshold, the distance detection module is triggered.

[0271] Furthermore, the infrared light emission range is a cone-shaped area directly in front of the smart wall switch 100. When there is a nearby object directly in front of the smart wall switch 100, the intensity of the infrared light reflected by the object increases, and the infrared light received by the infrared receiving unit 452 increases accordingly.

[0272] Furthermore, the infrared emitting unit 451 adopts an infrared light-emitting tube, and the infrared receiving unit 452 adopts an infrared receiving head.

[0273] Furthermore, such as Figure 16 and Figure 21 As shown, the middle shell 3 has an infrared emitting hole 341 at the position corresponding to the infrared emitting unit 451, and an infrared receiving hole 342 at the position corresponding to the infrared receiving unit 452. Both the infrared emitting hole 341 and the infrared receiving hole 342 are located within the area covered by the display cover plate 5.

[0274] Furthermore, such as Figure 18 As shown, the first coating 551 has hollowed out corresponding positions on the infrared emitting unit 451 and the infrared receiving unit 452 to form an infrared emitting area 53 and an infrared receiving area 54, respectively. The transmittance of visible light with a wavelength of 550nm through the infrared emitting area 53 and the infrared receiving area 54 is greater than 5% and less than 35%. Therefore, the infrared emitting area 53 and the infrared receiving area 54 appear black to the outside, consistent with the color of other areas of the display cover 5. The infrared emitting area 53 and the infrared receiving area 54 are visually hidden, and the display cover 5 presents a unified black effect.

[0275] Furthermore, the transmittance of infrared light with a wavelength of 940nm through both the infrared emitting area 53 and the infrared receiving area 54 is greater than 70% and less than 95%, to ensure the accuracy of the distance detection module. Furthermore, the back of the display cover 5 is covered with a third coating 553 on the infrared emitting area 53 and the infrared receiving area 54. The third coating 553 is a black transparent coating, ensuring that the transmittance of the infrared emitting area 53 and the infrared receiving area 54 reaches the target value.

[0276] Furthermore, such as Figure 18 As shown, the first coating 551 is hollowed out at the corresponding position of the display area 52 to form the display area 52; the back of the display cover 5 is covered with a fourth coating 554 on the display area 52. The fourth coating 554 is a black transparent coating, so that the transmittance of visible light with a wavelength of 550nm through the infrared emitting area 53 and the infrared receiving area 54 is greater than 5% and less than 35%. Therefore, when the screen 6 is not lit, the display area 52 appears black, consistent with the color of other areas of the display cover 5, and the display area 52 is visually hidden, giving the display cover 5 a unified black effect.

[0277] Furthermore, the second coating 552, the third coating 553, and the fourth coating 554 are the same coating. During production, this coating is first applied to the back of the display cover plate 5, and then the first coating 551 is applied on top of this coating.

[0278] Furthermore, such as Figure 29 As shown, a first enclosure space 391 is provided on the back of the middle shell 3 at the position corresponding to the infrared emitting hole 341. The infrared emitting unit 451 is placed inside the first enclosure space 391. A first enclosure wall is provided around the first enclosure space 391, surrounding the infrared emitting unit 451. A second enclosure space 392 is provided on the back of the middle shell 3 at the position corresponding to the infrared receiving hole 342. The infrared receiving unit 452 is placed inside the second enclosure space 392. A second enclosure wall is provided around the second enclosure space 392, surrounding the infrared receiving unit 452. This prevents the infrared light emitted by the infrared emitting unit 451 from propagating from inside the smart wall switch 100 to the infrared receiving unit 452, thereby preventing the infrared receiving unit 452 from being falsely triggered. The first and second enclosure walls extend from the back of the middle shell 3. Furthermore, the first and second enclosure walls respectively abut against the first circuit board 4 to prevent infrared light from passing through the gap between the first and second enclosure walls and the first circuit board 4.

[0279] Furthermore, such as Figure 29As shown, a plurality of baffles 393 are provided on the back of the middle shell 3 between the first enclosure space 391 and the second enclosure space 392. The baffles 393 extend on the back of the middle shell 3 and can further block the infrared light emitted by the infrared emitting unit 451 from propagating from the inside of the smart wall switch 100 to the infrared receiving unit 452, thereby preventing the infrared receiving unit 452 from being accidentally triggered.

[0280] In some embodiments, such as Figure 19 As shown, the first circuit board 4 is disposed on the side of the middle shell 3 opposite to the display cover plate 5, as... Figure 21 As shown, the middle shell 3 has a second touch hole 343 at the corresponding position of the touch area 51; as Figure 17 and Figure 27 As shown, the touch component 43 includes a sensing sheet 431 located on the first circuit board 4 and a conductive foam 432 located in the second touch hole 343. The conductive foam 432 abuts against the sensing sheet 431 and is sandwiched between the sensing sheet 431 and the display cover plate 5. The display cover plate 5 forms a touch area 51 at the corresponding position of the touch component 43.

[0281] exist Figure 27 In the diagram, the left side is a top view of the first circuit board 4, and the right side is a bottom view of the first circuit board 4.

[0282] Among them, such as Figure 27 As shown, the sensing sheet 431 is a thin metal sheet laid on the first circuit board 4 and electrically connected to the sensing chip. The conductive foam 432 is constructed as an elastic foam with conductive properties to extend the sensing height. The bottom of the conductive foam 432 abuts against the sensing sheet 431, and the top is directly or indirectly abutted by the display cover plate 5. The sensing sheet 431 and the conductive foam 432 serve as sensing electrodes, forming an electrostatic field. The sensing principle of the touch component 43 is capacitive touch sensing. The human body, as a conductor, changes the capacitance between the electrode and ground when touched. When the user's finger clicks the touch area 51, the finger and the conductive foam 432 form a coupling capacitance, changing the original capacitance value. The sensing chip detects the capacitance change and outputs relevant commands. Furthermore, the sensing chip is a microcontroller, and the sensing chip is soldered to the back of the first circuit board.

[0283] Furthermore, the sensing sheet 431 is square-shaped, and the light-emitting element 44 is located at the center of the square-shaped sensing sheet 431.

[0284] Furthermore, the light-diffusing sheet 57 is disposed between the conductive foam 432 and the display cover plate 5, and the display cover plate 5 is indirectly abutted against the top of the conductive foam 432 through the light-diffusing sheet 57.

[0285] like Figure 16 and Figure 19 As shown, the conductive foam 432 has a light guide hole 4321, which corresponds to the position of the light-emitting element 44. The light emitted by the light-emitting element 44 passes through the light guide hole 4321 and illuminates the indicator pattern 511, and then shines through the indicator pattern 511. Furthermore, the area of ​​the light guide hole 4321 in the horizontal direction can cover the area of ​​the indicator pattern 511.

[0286] like Figure 20 As shown, the connecting part 2 has a first touch hole 23, which is directly opposite to the second touch hole 343. The first touch hole 23 in the connecting part 2 integrates the touch component 43 and the connecting part 2 in the same position.

[0287] Furthermore, both the first touch hole 23 and the second touch hole 343 are square through holes, and the conductive foam 432 is a cuboid.

[0288] Furthermore, such as Figure 17 As shown, adhesive is provided on the back of the display cover 5, which is then attached to the middle shell 3 and the connecting part 2, thereby fixing the connecting part 2. Fixing the connecting part 2 prevents the button 1 from wobbling in the horizontal direction, and the positional relationship between the button 1 and the middle shell 3 is fixed. Using the display cover 5 to fix the connecting part 2 eliminates the need for an additional fixing structure, resulting in a simpler structure, reduced panel thickness, and improved assembly efficiency.

[0289] Furthermore, such as Figure 17 and Figure 16 As shown, the middle shell 3 includes a first surface for attaching the display cover plate 5, and the connecting part 2 includes a second surface that is flush with the first surface. The second surface and the first surface are used together to attach the display cover plate 5.

[0290] Furthermore, such as Figure 17 As shown, the adhesive on the back of the display cover 5 is set as double-sided adhesive 56, and the double-sided adhesive 56 has a hollowed-out area in the touch area 51, the display area 52, the infrared emitting area 53 and the infrared receiving area 54.

[0291] Furthermore, such as Figure 16 As shown, the middle shell 3 is provided with a positioning part 35, and the connecting part 2 is positioned and engaged with the positioning part 35 to ensure accurate positional relationship between the button 1 and the middle shell 3. The positioning part 35 can be a positioning post, a positioning groove, or other structure with positioning function. In an exemplary embodiment, as shown... Figures 20-22As shown, the positioning part 35 includes positioning walls 351 abutting against both sides of the connecting part 2, and positioning ribs 352 located at the four corners of the connecting part 2. Positioning grooves 21 are respectively provided at the four corners of the connecting part 2, and the positioning ribs 352 are embedded in the positioning grooves 21. Further, the positioning part 35 also includes a square positioning frame 353 arranged around the second touch hole 343. The square positioning frame 353 protrudes from the middle shell 3. A square positioning groove 22 is provided around the first touch hole 23 of the connecting part 2, and the square positioning frame 353 is embedded in the square positioning groove 22.

[0292] In some embodiments, such as Figure 21 As shown, the middle shell 3 is provided with a mounting groove 36, and the screen 6 is mounted in the mounting groove 36 through the opening side of the mounting groove 36. The opening side of the mounting groove 36 is closed by the display cover plate 5. Figure 28 As shown, the ribbon cable 61 of the screen 6 passes through the middle shell 3 and connects to the ribbon cable connector 46 of the first circuit board 4. The ribbon cable connector 46 is disposed on the lower surface of the first circuit board 4. Figure 28 This is a rear view of the middle shell 3 and the first circuit board 4.

[0293] Furthermore, the mounting groove 36 is a square groove, and each side wall of the mounting groove 36 is provided with a positioning protrusion. The positioning protrusion abuts against the side of the screen 6 so that the relative position of the screen 6 in the mounting groove 36 is accurate.

[0294] Furthermore, the back of the screen 6 is glued to the mounting slot 36 to facilitate the installation of the display cover 5.

[0295] Existing smart wall switches typically have a low-voltage circuit board and a high-voltage circuit board. The low-voltage circuit board is located in the middle shell, and a cover plate is installed at the bottom of the middle shell to cover the low-voltage circuit board. The high-voltage circuit board is located in a receiving groove in the bottom shell. Generally, the low-voltage circuit board and the cover plate cannot utilize the thickness of the bottom shell, which means that the low-voltage circuit board and the cover plate must occupy the thickness of the middle shell, resulting in a relatively thick middle shell.

[0296] To solve the above problems, in the embodiments of the present invention, such as Figures 28-31 As shown, the smart wall switch 100 also includes a bottom shell 7, which has a second receiving groove 71; a middle shell 3 is detachably connected to the bottom shell 7 and covers the opening side of the second receiving groove 71; wherein, the middle shell 3 has a first receiving groove 37 facing the bottom shell 7, the first receiving groove 37 is embedded in the second receiving groove 71, the first receiving groove 37 contains a first circuit board 4, and the first circuit board 4 can be detached from the bottom shell 7 along with the middle shell 3; the second receiving groove 71 contains a second circuit board 72, and the second circuit board 72 is electrically connected to the first circuit board 4.

[0297] In this embodiment of the invention, the first circuit board 4 is installed inside the first receiving groove 37, and the first receiving groove 37 is embedded in the second receiving groove 71 of the bottom shell 7. Thus, the first circuit board 4 borrows space from the bottom shell 7 in terms of thickness. When the bottom of the first receiving groove 37 is provided with a first cover plate 81, the first cover plate 81 is also placed in the second receiving groove 71. The first cover plate 81 and the first circuit board 4 do not occupy the thickness of the middle shell 3, and the panel of the smart wall switch 100 can be thinned, so that the smart wall switch 100 can achieve an ultra-thin panel design.

[0298] in, Figure 28 and Figure 29 These are all views from the back of the middle shell 3, such as Figure 29 As shown, the first receiving groove 37 can be a groove structure formed by the mutual enclosure of each side wall, or it can be a groove structure in which the side walls are not completely enclosed.

[0299] Furthermore, the first circuit board 4 is a low-voltage circuit board used to carry low-voltage circuits, and the second circuit board 72 is a high-voltage circuit board used to carry high-voltage circuits. The second circuit board 72 is equipped with a power module and a relay. The power module is connected to 220V AC power and converts the AC power into low-voltage DC power to provide power to the low-voltage circuits. The relay is connected to the controlled lighting fixtures to control the on / off state of the lighting fixtures.

[0300] Furthermore, such as Figure 31 and Figures 21-22 As shown, the button 1 is located on the side of the middle shell 3 facing away from the bottom shell 7. A first recess 38 is provided on the side of the middle shell 3 facing the button 1. The first recess 38 is located within the corresponding area of ​​the first receiving groove 37. When the button 1 is pressed, a portion of the button 1 sinks into the first recess 38. Thus, the first groove utilizes the space of the bottom shell 7 to provide downward pressure space for the button 1, which helps to reduce the panel thickness. The corresponding area of ​​the first receiving groove 37 can be understood as the area directly above the first receiving groove 37. The first recess 38 being located within the corresponding area of ​​the first receiving groove 37 can be understood as the projected shape formed by the first receiving groove 37 projecting onto the middle shell 3 covering the first recess 38.

[0301] Furthermore, such as Figures 21-22 As shown, the button support 13 of button 1 has an edge rib 133 near the edge. The first recess 38 includes an edge recess located at the edge of the first recess 38. The shape of the edge recess is adapted to the edge rib 133. When button 1 is pressed, the edge rib 133 sinks into the edge recess.

[0302] Furthermore, such as Figures 21-22As shown, the button 1 is provided with a latching part 132 for latching the middle shell 3. The latching part 132 is located within the corresponding range of the first recess 38, that is, the latching part 132 is located in the area directly above the first receiving groove 37 of the bottom shell 7. The latching part 132 can use the space of the first receiving groove 37, so that the latching part 132 does not occupy the thickness of the middle shell 3, which is conducive to realizing the ultra-thin panel design.

[0303] The snap-fit ​​part 132 snaps into the snap-fit ​​position 33 of the middle shell 3, and the snap-fit ​​position 33 is located in the area of ​​the first groove. The technical details of the snap-fit ​​part 132 and the snap-fit ​​position 33 have been described in detail above, and will not be repeated here.

[0304] Furthermore, such as Figures 21-22 As shown, the first circuit board 4 is provided with an electronic switch 41 at the corresponding position of each button 1. Each button 1 is provided with a trigger part 131 for triggering the electronic switch 41. The trigger part 131 is located within the corresponding range of the first recess 38, which is beneficial for realizing an ultra-thin panel design.

[0305] In some embodiments, such as Figure 21 and Figure 35 As shown, a second recess 381 is provided on the side of the middle shell 3 facing the button 1, and the second recess 381 is located around the first recess 38. The function of the second recess 381 is as follows: Figure 35 As shown, when button 1 is composed of a button bracket 13 made of plastic material and a button 1 cover made of glass material, in order to make the button bracket 13 and the button 1 cover bond stably, the area of ​​the button bracket 13 will increase, causing the button bracket 13 to exceed the range of the first recess 38. Therefore, in this embodiment, a second recess 381 is provided around the first recess 38, and the second recess 381 provides a downward pressure space for the button bracket 13.

[0306] Furthermore, such as Figures 34-35 As shown, the button 1 consists of a button bracket 13 and a button plate 14. The button plate 14 is glued and fixed to the upper surface of the button bracket 13. When the button 1 is pressed, the button bracket 13 sinks into the second recess 381.

[0307] Furthermore, such as Figure 34As shown, the button bracket 13 has an annular glue groove 135 on the side facing the button plate 14. The annular glue groove 135 is used for applying glue so that the button plate 14 is attached to the button bracket 13. The annular glue groove 135 is recessed at the center of the connecting part 2 to form a recessed section 1351, thereby leaving a deformation space between the recessed section 1351 and the connecting part 2. When the button 1 is pressed, the connecting part 2 connected to the button 1 and the part near the connecting part 2 will undergo a large deformation. The recessed section 1351 can avoid the part with large deformation and prevent the button plate 14 from delaminating with the button bracket 13.

[0308] In some embodiments, such as Figure 29 As shown, where Figure 29 From the rear view of the middle shell 3, the middle shell 3 is provided with a plurality of surrounding walls 371 protruding toward the bottom shell 7. The surrounding walls 371 surround each other to form the first receiving groove 37 inside the surrounding walls 371, and the surrounding walls 371 are received in the second receiving groove 71.

[0309] Furthermore, such as Figure 30 As shown, a first cover plate 81 is provided at the bottom of the first receiving groove 37, the first circuit board 4 is disposed in the space between the first cover plate 81 and the first receiving groove 37, and the second circuit board 72 is disposed outside the space between the first cover plate 81 and the first receiving groove 37. When the middle shell 3 is removed from the bottom shell 7, the first circuit board 4 and the first cover plate 81 are removed from the bottom shell 7 together with the middle shell 3.

[0310] The bottom shell 7 has mounting holes 74 on both sides. When installing the smart wall switch 100, the middle shell 3 must first be removed from the bottom shell 7 to expose the mounting holes 74. The mounting holes 74 are connected to the wall junction box by connecting screws, thereby fixing the bottom shell 7 to the wall. The mounting holes 74 are countersunk holes, and the nuts of the connecting screws are accommodated in the mounting holes 74.

[0311] The surrounding wall 371 is a vertical wall. The surrounding wall 371 can completely surround the side of the second receiving groove 71, or it can only surround a portion of the side, leaving the other portion open. In an exemplary embodiment, as... Figure 29 and Figure 28 As shown, the surrounding wall 371 is broken in the corresponding area of ​​the two mounting holes 74, so that the two sides of the first circuit board 4 are not blocked by the surrounding wall 371. The user can pinch the two sides of the first circuit board 4 to assemble the first circuit board 4 into the middle shell 3, making the assembly more convenient.

[0312] Furthermore, such as Figure 30 and Figure 26As shown, U-shaped walls 811 extend from both sides of the first cover plate 81 toward the middle shell 3. The cross-section of the U-shaped wall 811 is a concave U-shape. The position of the U-shaped wall 811 corresponds to the break area of ​​the surrounding wall 371. The U-shaped wall 811 is used to close the break area of ​​the surrounding wall 371, so that the first circuit board 4 is closed between the first receiving groove 37 and the first cover plate 81.

[0313] Furthermore, such as Figure 30 As shown, the two sides of the surrounding wall 371 are respectively snapped into the first end cap.

[0314] Furthermore, such as Figures 30-32 As shown, a second cover plate 82 is disposed within the second receiving groove 71, dividing the second receiving groove 71 into an upper space and a lower space. The first receiving groove 37 is located in the upper space, and the second circuit board 72 is located in the lower space. The first circuit board 4 and the second circuit board 72 are electrically connected through a pin header 47 and a female header 721. The first cover plate 81 has a first through hole 813 at the corresponding position of the pin header 47, and the second cover plate 82 has a second through hole 822 at the corresponding position of the first through hole 813. One of the pin header 47 and the female header 721 is disposed on the first circuit board 4, and the other is disposed on the second circuit board 72. In an exemplary embodiment, the pin header 47 is disposed on the lower surface of the first circuit board 4, and the female header 721 is disposed on the upper surface of the second circuit board 72. The pin header 47 is exposed through the first through hole 813, and the female header 721 is exposed through the second through hole 822.

[0315] Furthermore, such as Figure 32 As shown, the two ends of the second cover plate 82 are respectively snapped into the inner wall of the second receiving groove 71. The second circuit board 72 is clamped and fixed by the second end cover and the bottom shell 7.

[0316] Furthermore, such as Figure 30 and Figure 31 As shown, a wireless communication module 48 is provided on the lower surface of the first circuit board 4, the upper surface of the first cover plate 81 is recessed downward at the position corresponding to the wireless communication module 48, the lower surface of the first cover plate 81 protrudes downward at the position corresponding to the wireless communication module 48 to form a protrusion 812, and the second cover plate 82 is recessed downward at the position corresponding to the protrusion 812 to form a recess 821.

[0317] Furthermore, such as Figures 31-33As shown, the lower end of the second circuit board 72 is provided with multiple wiring terminals, including wiring screws 722. An operating hole 73 is formed on the side of the bottom shell 7, directly opposite the wiring screws 722. A user can use a screwdriver to operate the wiring screws 722 through the operating hole 73. The wiring screws 722 are confined inside the operating hole 73 and cannot be disengaged. A distance-increasing ring 731 protrudes outward from the outer edge of the operating hole 73. The distance-increasing ring 731 increases the distance between the wiring screws 722 and the outside, preventing the user's fingers from touching the wiring screws 722 and causing electric shock.

[0318] In some embodiments, such as Figure 28 As shown, the first circuit board 4 is directly fixedly connected to the middle shell 3; wherein, the first circuit board 4 is fixedly connected to the middle shell 3 by circuit board screws 491, or the first circuit board 4 is snap-fitted to the middle shell 3. Because the first circuit board 4 is directly fixed to the middle shell 3, the positional relationship between the first circuit board 4 and the middle shell 3 is stable, thereby providing stable support for the electronic switch 41 by the first circuit board 4, ensuring that the button 1 can stably trigger the electronic switch 41 within a short stroke, laying the foundation for achieving an ultra-thin panel.

[0319] In an exemplary embodiment, such as Figures 27-29 As shown, the first circuit board 4 is provided with four connection holes 49. The back of the middle shell 3 is provided with a connecting post 344 at the corresponding position of each connection hole 49. A connecting seat is provided at the root of the connecting post 344. The connecting post 344 is inserted into the connection hole 49 to position the circuit board in the horizontal direction. The circuit board abuts against the connecting seat to make the circuit board accurately positioned in the vertical direction. Each connecting post 344 is screwed into a circuit board screw 491, and the circuit board screw 491 fixes the first circuit board 4 to the middle shell 3.

[0320] Corresponding to the above-described smart wall switch embodiments, this disclosure also provides a control method in some embodiments, applied to the smart wall switch or the processor.

[0321] In some embodiments, the control method includes:
