Furthermore, the connection methods between traditional keyboards and smart terminals are limited, resulting in a poor interactive experience. They also fall short in areas such as personalized display, voice control, and quick pairing with multiple devices, making it difficult to meet users' higher demands for keyboard functionality, intelligence, and user experience. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a multi-functional keyboard with a display screen.

[0004] To achieve the above objectives, this utility model provides a multi-functional keyboard with a display screen, comprising a housing, key units, a lighting unit, a display unit, a voice control unit, and a control board unit disposed on the housing. The key units, lighting unit, display unit, and voice control unit are all electrically connected to the control board unit. The control board unit receives and processes input signals from the key units and voice control unit and outputs control signals to the lighting unit and display unit. The display unit includes multiple LED display modules arranged in a matrix and electrically connected to the control board unit. An external smart terminal is electrically connected to the control board unit, and the external smart terminal sends a switching command to the control board unit, which then switches the display unit to show image / text information or music / rhythm information.

[0005] By integrating key units, lighting units, display units, voice control units, and control board units, the keyboard achieves a combination of input functions with diverse displays and intelligent interaction. The LED display module can flexibly display images, text, or musical rhythm information, enhancing the keyboard's functionality and visual experience. The cooperation between the voice control unit and the lighting unit enhances the convenience and fun of interaction. The housing serves as the supporting foundation, the key units are responsible for input operations, the voice control unit collects sound signals, and the control board unit processes the signals from each unit to drive the lighting unit to display corresponding light effects. At the same time, it controls the LED display module matrix of the display unit to display the required information. All units work together to achieve multi-functional integration.

[0006] The display unit includes an LED board, a snap-fit ​​component disposed on the LED board, and a snap-fit ​​groove formed on the snap-fit ​​component. A snap-fit ​​component is formed on the housing component, and the LED board can be detachably snapped onto the snap-fit ​​component via the snap-fit ​​groove of the snap-fit ​​component.

[0007] The LED board features a snap-fit ​​component with a locking slot, which engages with a snap-fit ​​component on the housing to form a detachable snap-fit ​​connection, achieving a secure connection and quick assembly / disassembly between the LED board and the housing. The benefits are significant: firstly, this structural design ensures the stability of the LED board after installation, guaranteeing that the display function is not affected by loosening during use; secondly, the detachable snap-fit ​​method allows users to easily disassemble, replace, or repair the LED board, greatly improving the ease of keyboard maintenance and the flexibility of component replacement. Users can flexibly adjust the display unit according to their needs, further enhancing the product's practicality and user experience.

[0008] The display unit also includes a control button on the housing, which is electrically connected to the control board unit. The control button is used to control the keyboard characters, patterns, music rhythm effects, and other modes displayed on the LED board.

[0009] By incorporating a control button electrically connected to the control board unit within the housing, a direct and convenient operation interface is provided for the user. This allows for quick switching between various display modes on the LED board, such as keyboard characters, patterns, and music rhythm effects, without relying on additional equipment or complex operations. This enhances the interactive flexibility of the display unit and the user experience, meeting personalized display needs in different scenarios. Specifically, the control button is installed at a preset position on the side of the LED board and electrically connected to the control board unit. When the user presses the control button, the button sends a corresponding mode switching signal to the control board unit. Upon receiving the signal, the control board unit drives the LED board to switch to the corresponding display mode, enabling real-time control of the displayed content.

[0010] The lighting unit includes a backlight mounted on the button unit, a side light mounted on at least one side of the housing, and a light strip mounted on the side of the button unit; the backlight, side light, and light strip display different lighting effects according to the volume of the music or sound on the smart terminal.

[0011] By setting up a lighting unit consisting of backlights, side lights, and light strips, a multi-dimensional lighting display effect is achieved. The lighting can change with the volume of music or sound on the smart terminal to present different lighting effects. This not only enhances the ease of use of the keyboard in low-light environments, but also improves the atmosphere and interactive fun through the linkage of light and sound, meeting the user's personalized and immersive experience needs. The specific implementation method is as follows: a backlight is arranged on the key unit to illuminate the key, side lights are set on the side of the housing, and light strips are set on the side of the key unit. After receiving the music signal from the smart terminal or the sound signal collected by the voice control unit, the control board unit generates corresponding control commands according to the signal strength or frequency changes, driving the backlights, side lights, and light strips to present synchronous or differentiated changes in brightness, color, and flashing frequency, forming a dynamic lighting effect that is linked with the sound.

[0012] The control board unit includes a main control chip, a battery module, and a smart terminal interaction module. The button unit, light unit, display unit, voice control unit, battery module, and smart terminal interaction module are all electrically connected to the main control chip.

[0013] The light strip includes a light groove on the housing and a light-emitting strip housed in the light groove; the external power supply charges the battery module via a plug interface, and the control board unit converts the charging status data of the battery module into a light effect that displays the charging status via the light-emitting strip.

[0014] The combination of the light groove and the light strip effectively protects and fixes the light strip while ensuring a stable lighting effect. Simultaneously, the light strip displays the charging status, allowing users to intuitively understand the battery module's charging progress (e.g., different colors correspond to different battery levels, flashing frequency indicates charging, and constant light indicates full charge), improving ease of use. Specifically, a light groove adapted to the size of the light strip is created on the housing. The light strip is embedded in the light groove and electrically connected to the main control chip of the control board unit. When an external power source charges the battery module through the interface, the main control chip acquires the battery power data in real time, converts it into corresponding lighting control signals, and transmits them to the light strip. This allows the light strip to intuitively display the charging status through preset color changes, brightness adjustments, or flashing modes.

[0015] The sound control unit includes a microphone mounted on the housing. The microphone is used to pick up external sounds and transmit the sound data to the main control chip. The main control chip adjusts the light effect of the lighting unit according to the sound level.

[0016] By setting a microphone on the housing as the core component of the voice control unit, it can collect external sound information in real time and transmit it to the control board unit. The control board unit can then dynamically adjust the lighting effect of the lighting unit according to the sound level, realizing intelligent linkage between sound and light. This not only enhances the interactive fun and immersive experience of the keyboard, but also allows for triggering lighting changes without manual operation, improving ease of use. The specific implementation method is as follows: the microphone is embedded in the preset mounting position of the housing and electrically connected to the control board unit. The microphone continuously receives external sound and converts it into electrical signals, which are then transmitted to the control board unit. After analyzing and processing the intensity of the sound signals, the control board unit generates corresponding control commands and sends them to the lighting unit, causing the backlight, side lights, and light strips to exhibit corresponding brightness changes, color switching, or flashing frequency adjustments according to the sound level.

[0017] The display unit includes a TFT screen electrically connected to the main control chip and mounted on the housing. The TFT screen is used to receive signals transmitted by the main control chip and display the time, computer system mode, computer indicator light status, keyboard mode, and patterns. The button unit is provided with a screen display switching button electrically connected to the main control chip. The screen display switching button is used to switch the content displayed on the TFT screen.

[0018] The TFT screen can centrally display various key information such as time, computer and keyboard modes, allowing users to quickly obtain important content without switching device interfaces. The screen display switching button in the button unit can conveniently switch the content displayed on the TFT screen, further improving the flexibility and efficiency of information acquisition and enriching the functionality of the keyboard. The specific implementation method is as follows: the TFT screen is installed in a suitable position on the housing and connected to the control board unit. The control board unit transmits various information signals to the TFT screen for display. When the user presses the screen display switching button, the button sends a switching signal to the control board unit, which then instructs the TFT screen to switch to the next preset display content, realizing convenient switching of displayed information.

[0019] The control board unit also includes an NFC module, a Bluetooth module, a wireless communication module, and a USB module electrically connected to the main control chip. The NFC module is used to establish a pairing connection with an external smart terminal that supports NFC functionality through near-field communication. The Bluetooth module is used to establish a pairing connection with an external smart terminal that supports Bluetooth functionality. The wireless communication module establishes a pairing connection with an external smart terminal via a wireless communication protocol. The USB module establishes a pairing connection with an external smart terminal via an external data connection cable.

[0020] This control board unit integrates an NFC module, Bluetooth module, wireless communication module, USB module, and other components electrically connected to the main control chip. Storage module This device enables diverse pairing and connection methods with external smart terminals. The NFC module supports fast near-field pairing, offering convenient and efficient operation; the Bluetooth module provides a stable connection with Bluetooth-enabled terminals, meeting daily short-range communication needs; the wireless communication module expands the connection range and scenarios through wireless communication protocols; and the USB module provides a reliable wired connection via a data cable, ensuring stable data transmission. The coexistence of multiple connection methods greatly enhances the device's versatility, compatibility, and flexibility, adapting to the connection needs of different users in various scenarios. The storage module stores relevant authentication information and historical connection records required during the pairing and connection process between the keyboard and external smart terminals, facilitating the pairing process in subsequent connections.

[0021] The display unit also includes a capacitive touchscreen mounted on the LED board, which is electrically connected to the main control chip. The touchscreen is used to receive touch operation commands from the user and transmit them to the main control chip. The control board unit performs corresponding function adjustments according to the touch commands. The edge of the touchscreen is provided with an anti-accidental touch sensing area, which automatically blocks the touch response of the corresponding area when an unintended touch is detected.

[0022] A capacitive touchscreen is integrated into the LED board and connected to the main control chip, providing users with a touch interaction method in addition to buttons. This allows for intuitive and convenient function control, enhancing operational flexibility. Meanwhile, an anti-mistouch sensing area at the edge of the touchscreen effectively identifies and blocks unintended touches, reducing accidental operations and ensuring a smooth user experience. Specifically, the capacitive touchscreen is integrated onto the LED board surface and electrically connected to the control board unit. Users issue operation commands via touch, which are processed by the control board unit to execute corresponding function controls. Simultaneously, the anti-mistouch sensing area continuously detects touch signals in the edge area. When an unintended touch (such as a palm strike) is detected, the touch response in that area is automatically blocked, ensuring accurate execution of effective operations.

[0023] The beneficial effects of this utility model are as follows: By coordinating the work of components such as the button unit, lighting unit, display unit, and voice control unit through the control board unit, an organic integration of input, display, and interaction is achieved. The button unit ensures basic input, the display unit (including LED display module, TFT screen, and capacitive touch screen) provides diversified information display and touch operation, the voice control unit and lighting unit realize sound and light-shadow linkage, the NFC module simplifies device pairing, and the detachable LED board structure improves maintenance flexibility. It not only breaks through the limitations of traditional keyboards with their single function, but also enhances functionality and intelligence through multi-dimensional display (images, text, rhythmic information, etc.) and multi-mode interaction (buttons, touch, voice control, near-field communication). Furthermore, it improves ease of use and user experience through details such as anti-mistouch design, convenient disassembly and assembly structure, and dynamic lighting effects, meeting users' diverse needs in terms of personalization, immersion, and efficient interaction.
