[0001] This utility model relates to the field of keyboard technology, and in particular to a keyboard base and keyboard based on modular expansion. Background Technology
[0002] With the widespread adoption and diversification of electronic devices, keyboards, as an important tool for human-computer interaction, face increasingly complex functional and design requirements. Traditional keyboards typically have a fixed functional layout, making it difficult to meet users' needs for personalization and multi-functionality. For example, users may require additional functional modules (such as touchpads, shortcut keys, displays, etc.) to improve operational efficiency, but existing keyboard designs cannot flexibly expand or replace these modules.
[0003] Furthermore, while some modular keyboard designs exist in existing technologies, their expansion methods are often limited, the connection between the modules and the keyboard body is not robust or flexible enough, and there is a lack of a unified interface standard, resulting in poor compatibility and inconvenience. Therefore, there is an urgent need for a keyboard dock and supporting system that can achieve flexible expansion, stable connection, and strong compatibility. Utility Model Content

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.
[0032] Firstly, referring to Figures 1 to 4 This embodiment provides a keyboard dock based on modular expansion, including a dock body 1, which is divided into an expansion area 10 and a fixed area 20.
[0033] The surface of the extension area 10 is provided with a plurality of mating protrusions 11, which are arranged in a regular manner, and each mating protrusion 11 has a predetermined geometric shape and size;
[0034] The expansion area 10 is configured to dock with expansion modules 30 of various shapes and sizes. The bottom of the expansion module 30 is provided with a docking recess that matches a combination of protrusions arranged by a number of docking protrusions 11. The expansion module 30 is detachably fixed to the expansion area 10.
[0035] It should be noted that modular functional expansion is achieved by dividing the base body 1 into an expansion area 10 and a fixed area 20. The upper surface of the base body 1 is rectangular, with the upper area being the expansion area 10 and the lower area being the fixed area 20. The surface of the expansion area 10 has multiple regularly arranged mating protrusions 11. These protrusions have predetermined geometric shapes and sizes, and several mating protrusions 11 are arranged to form a protrusion combination. This protrusion combination can precisely match the mating recess at the bottom of the expansion module 30. The regular arrangement of the mating protrusions 11 constitutes a standardized interface, adapting to expansion modules 30 of different sizes, and the height of the mating protrusions 11 matches the depth of the recess, forming a physical limit.
[0036] When users need to expand functionality, they can simply align the mating recess of the expansion module 30 with the protrusion at the appropriate position and press it down to quickly install the module. This design not only simplifies the module connection process but also ensures a stable connection through optimized geometry, preventing the module from loosening or falling off during use. Furthermore, the modular design allows users to freely combine expansion modules 30 with different functions according to their needs, significantly improving the keyboard's flexibility and versatility.
[0037] In some possible implementations, the surface of the expansion area 10 is provided with 6×30 docking protrusions 11, and the docking recess of the expansion module 30 includes sizes such as 6×8 and 6×4. Users can select a suitable position and snap the docking recess into the protrusion combination of the corresponding size to form a fixed position.
[0038] In one implementation, the fixed area 20 is divided into at least one fixed docking area 21. Each fixed docking area 21 is provided with a docking port 22 for docking functional modules and providing power and data interaction. The docking port 22 integrates both power and data pins. When a functional module is connected to the docking port 22, the base provides a stable power supply to the functional module through the docking port 22, achieving efficient data transmission. This design solves the problems of inconvenient power supply and data transmission in traditional keyboard expansion modules, allowing users to achieve normal operation of the functional modules without additional connecting cables or power adapters. At the same time, the design of the fixed docking area 21 makes the installation of functional modules more convenient, allowing users to replace or upgrade functional modules at any time as needed, improving the keyboard's scalability and efficiency.
[0039] In one implementation, the base body 1 is connected to a USB expansion device, which connects to the expansion module 30 on the expansion area 10 via a wired connection. When the user needs to expand functionality, the USB expansion device provides a stable data transmission channel for the expansion module 30, ensuring efficient communication between the module and the computer or other host devices. This design not only solves the problem of inconvenient data transmission in traditional keyboard expansion modules but also improves the stability and reliability of data transmission through a wired connection. Furthermore, the USB expansion device is simple and convenient to connect to, allowing users to expand functionality without complex settings, thus enhancing the user experience. Moreover, the rear of the base body 1 is equipped with a USB interface for connecting to a computer host or other devices.
[0040] In one implementation, the base body 1 is equipped with a wireless transceiver device, which wirelessly connects to the expansion module 30 on the expansion area 10. When the user needs to expand functionality, the wireless transceiver device provides a stable wireless data transmission channel for the expansion module 30, supporting communication protocols such as Bluetooth and Wi-Fi. This design not only solves the problem of inconvenient wired connections in traditional keyboard expansion modules but also improves the keyboard's flexibility and portability through wireless connectivity. Users can freely use the expansion module 30 without being restricted by cables, enhancing the convenience and comfort of operation.
[0041] It should be noted that the connection between the expansion module 30 and the base body 1 can be either a wired connection or a wireless connection. Regardless of the connection method, it is within the protection scope of this application.
[0042] In one implementation, the mating surfaces of the mating protrusion 11 and the mating recess are equipped with a locking structure. This locking structure is a magnetic component or a spring-loaded latch, connected via a snap-fit or magnetic connection. When the user installs the expansion module 30 onto the base, the locking structure automatically secures the module to the base, ensuring a stable and reliable connection between the module and the base. This design, through mechanical locking or magnetic adsorption, prevents the module from loosening or falling off during use, improving the keyboard's stability and security. Simultaneously, the locking structure design makes module installation and removal more convenient, allowing users to replace or upgrade modules as needed, enhancing the keyboard's flexibility and efficiency.
[0043] In one implementation, the mating protrusion 11 is cylindrical or square in shape, with a chamfered or rounded top, similar to the connecting pillar shape of Lego bricks. This design not only facilitates the installation and removal of modules but also reduces wear on the modules and base during installation through geometric optimization, extending the lifespan of the device. When the user installs the expansion module 30 onto the base, the chamfered or rounded design of the mating protrusion 11 guides the module to precise alignment, simplifying the installation process.
[0044] Secondly, combining Figure 5 and Figure 7 This embodiment provides a keyboard 40, which includes a keyboard base based on module expansion as described in the above embodiment, and also includes an expansion module 30 and a function module 50;
[0045] The expansion module 30 is fixed to the expansion area 10 of the keyboard base, and the function module is fixed to the fixing area 20 of the keyboard base.
[0046] When users need to expand functionality, they simply install the expansion module 30 and function module 50 into the corresponding areas to achieve this expansion. This design, through modular design and optimized standardized interfaces, enables flexible expansion and efficient connection of keyboard functions. Users can freely combine modules with different functions according to their needs, significantly improving the keyboard's flexibility and applicability. At the same time, the modular design also facilitates keyboard upgrades and maintenance; users can replace or upgrade modules at any time as needed without replacing the entire keyboard, reducing usage costs.
[0047] Among them, the expansion module 30 includes, but is not limited to, the following modules:
[0048] Shortcut key module: Integrates multiple programmable keys, allowing users to customize key functions according to their needs, such as quickly launching applications, executing macro commands, etc., suitable for gamers or professional users.
[0049] Knob or slider module: Provides physical knobs or sliders for adjusting volume, brightness, parameters, etc., suitable for audio editing, video editing and other scenarios.

[0051] Fingerprint recognition module: Provides biometric recognition functionality for quickly unlocking devices or authenticating identities, suitable for scenarios with high security requirements.
[0052] Wrist rest module: Provides an ergonomically designed wrist rest to relieve wrist fatigue during prolonged keyboard use, suitable for office work or long-term use scenarios.
[0053] Functional module 50 includes, but is not limited to, the following modules:
[0054] Keyboard module: Used to provide standard keyboard input functions. The docking port 22 provides power and data interaction support for the keyboard module. It can be designed as a full-size keyboard, a compact keyboard, or a split keyboard to meet the needs of different users. The keyboard module is connected to the docking position of the fixed area 20 through the keyboard connection spring pin and is limited by a magnetic structure.
[0055] Touchpad module: It provides cursor control and gesture operation functions similar to those of a laptop touchpad. The docking port 22 provides power and data interaction support for the touchpad module. The surface of the touchpad module adopts a high-sensitivity touch panel, which supports multi-touch and gesture operation.
[0056] Compared to existing technologies, the above embodiments provide a keyboard dock and keyboard based on modular expansion. Through modular design, the keyboard's functionality can be flexibly expanded, and its beneficial effects are mainly reflected in the optimization and innovation of its technical principles. First, the dock body 1 is divided into an expansion area 10 and a fixed area 20. The expansion area 10 has multiple regularly arranged mating protrusions 11. This design not only provides a unified interface standard for the expansion modules 30, but also ensures precise matching between the modules and the dock through optimized geometry and size. This standardized interface design allows users to freely combine expansion modules 30 of different shapes and sizes according to their needs, significantly improving the keyboard's compatibility and applicability.
[0057] Secondly, the fixed area 20 is equipped with a docking port 22 for connecting functional modules and providing power and data interaction. This design solves the problems of inconvenient power supply and data transmission in traditional keyboard expansion modules through a unified power and data interface. Functional modules can directly obtain power from the base and achieve data interaction without the need for additional connecting cables or power adapters, simplifying the usage process and improving the user experience. In addition, the base body 1 can connect to USB expansion devices or wireless transceivers, supporting both wired and wireless connection methods, further enhancing the system's flexibility and applicability.
[0058] Regarding connection stability, the mating surfaces of the mating protrusion 11 and the mating recess are equipped with locking structures, such as snap-fit or magnetic connections. This design ensures a secure and reliable connection between the module and the base through mechanical locking or magnetic adsorption, preventing the module from loosening or falling off during use. Meanwhile, the mating protrusion 11 is cylindrical or square in shape with chamfered or rounded corners at the top. This design not only facilitates module installation and disassembly but also reduces wear and tear on the module and base during installation, extending the equipment's lifespan.
[0059] From a technical perspective, this invention achieves flexible expansion and efficient connectivity of keyboard functions through modular design and optimized standardized interfaces. This design not only solves the problems of traditional keyboards' limited functionality and inconvenient expansion, but also improves user efficiency and satisfaction through a robust connection method and user-friendly experience. Furthermore, the modular design facilitates keyboard upgrades and maintenance, allowing users to replace or upgrade modules as needed without replacing the entire keyboard, thus reducing operating costs.
[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
