[0031] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] In the drawings, the thickness, size and shape of objects have been slightly exaggerated for ease of explanation. The drawings are only examples and are not drawn strictly to scale.

[0033] Unless otherwise defined, all terms (including technical terms and scientific terms) used in this article have the same meaning as commonly understood by ordinary technicians in the field to which this application belongs. It should also be understood that terms (such as terms defined in commonly used dictionaries) should be interpreted as having the same meaning as their meaning in the context of the relevant technology, and will not be interpreted in an idealized or overly formal sense unless explicitly defined in this article.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] The utility model embodiment, the interactive modular multifunctional keyboard can be combined, such as Figure 1 As shown, including:

[0036] The mounting shell 1 has a mounting surface which is an embedded flange, and the mounting surface is provided with a plurality of screw holes for mounting the keyboard module. The top of the mounting shell 1 is provided with a plurality of cable interfaces, and the thickness of the mounting shell 1 is not less than the maximum thickness of the keyboard module;

[0037] The keyboard module is installed at the corresponding screw hole position in the flange, and the keyboard module at least includes a programmable display keyboard module 2, an alphabetic keyboard module 3, and a numeric keyboard module 4.

[0038] The keyboard provided in this embodiment will be described in detail below.

[0039] refer to Figures 1 to 4 This embodiment adopts modular custom design, and designs the letter keyboard, numeric keyboard and programmable display keyboard into three independent modules, each of which can work independently. The scheme consists of 4 parts: letter keyboard module 3, numeric keyboard module 4, programmable display keyboard module 2 and the whole machine housing.

[0040] The mounting surfaces of the three modules are designed as rectangular shells with the same width, and they can be installed side by side in a whole machine shell, so that the relative positions of the three modules can be interchanged. The three modules are fixed on the flange of the whole machine shell by screws on the upper and lower frames. The flange of the whole machine shell mounting module is designed with evenly spaced sequence screw holes, so that no matter how the relative positions of the three modules are adjusted, the screws of the upper and lower frames of the modules can have corresponding screw holes on the flange of the whole machine shell. The whole machine shell can be designed in different forms according to different installation positions. The bottom of the shell is flat, which is convenient for installation on the desktop or frame. When installed on the frame, the whole machine shell is designed with an external mounting flange. There are several openings on the top of the whole machine shell to facilitate the external connection of cables for each module. The thickness of the whole machine body is designed according to the thickest module among the three modules to ensure that all modules can be installed in the whole machine shell.

[0041] That is to say, the three modules of the alphabetic keyboard, the numeric keyboard and the programmable display keyboard can be installed in interchangeable relative positions and fixed to the whole machine housing with screws. The back wire outlet hole 5 is opened at the rear of the whole machine housing for the rear wiring of the three modules (specifically through the rear connector 6 of the module); the distribution of the openings should be able to ensure that the three modules have corresponding outlets when arranged in any relative position; the module can be separated from the external cable, and the interface can use an ordinary connector or a circular connector for vibration resistance and waterproofing.

[0042] refer to Figure 5 to Figure 6 , the letter keyboard module 3 adopts a standard mechanical axis keyboard module, which consists of a keyboard circuit (including circuit board, key axis, middle plate, key cap, indicator light, socket, etc.) and a front panel. The keys include 26 English letters, numbers 0-9 and punctuation marks, uppercase and lowercase, tab, shift, ctrl, enter, F1-F24, ESC, delete, direction keys and other buttons. The standard mechanical axis keyboard module adopts an aluminum alloy upper shell and bottom plate, and the overall structure is assembled by silicone + mechanical axis positioning hole glue sealing treatment + waterproof silicone strip + aluminum alloy bottom plate + screws to achieve "complete sealing", so that water vapor cannot enter the keyboard from the front keys to achieve waterproof and shock-resistant effects. The module can be used independently and has a USB or other serial interface. A 114-key keyboard can be selected, and there can be a variety of layout forms.

[0043] refer to Figure 7 , the numeric keyboard module 4 adopts a standard mechanical axis keyboard module, which consists of a keyboard circuit (including a circuit board, a key axis, a middle plate, a key cap, a socket, etc.) and a front panel. The keys include 0-9, four arithmetic operations, a dot, and a carriage return and backspace key, and are arranged in a regular pattern. The standard mechanical axis keyboard module adopts an aluminum alloy upper shell and bottom plate. The overall structure is assembled with silicone + mechanical axis positioning hole glue sealing treatment + waterproof silicone strip + aluminum alloy bottom plate + screws to achieve "complete sealing" so that water vapor cannot enter the keyboard from the front keys to achieve waterproof and shock-resistant effects. The module can be used independently and has a USB or other serial interface.

[0044] refer to Figures 8 to 11The programmable display keyboard module 2 is composed of several programmable display buttons, a display driver board, a power supply component and a key control board. Each button is divided into two parts: a display component and a key base component. The display component mainly includes a protective glass 9, an OLED display screen 10, an outer shell 11, an adapter plate 12 and a pressure rod 13 (including a limit slot 7 and a corresponding limit screw 8); the protective glass is bonded to the display screen through optical glue, and its shielding layer is conductively connected to the metal outer shell to achieve shielding. Its surface is processed to achieve low reflection and anti-fingerprint effects, ensuring the electromagnetic compatibility and vibration resistance of the display component. The key base component includes a base 15 (including a guide groove, and a flexible belt 14 is arranged on the outside), a compression spring 16, a key shrapnel 17 and a key board 18; by reasonably selecting the compression spring material, designing the compression spring diameter and the number of turns, the programmable display button has good pressing performance.

[0045] Each programmable button can be 0.78in in size, with an aspect ratio close to 1:1, and can be laid out in a matrix format of 3 rows and 5 columns, or the number of rows and columns can be increased or shortened depending on the space allowed.

[0046] The buttons of the programmable display keyboard module 2 have both key and display functions. Each button consists of a display component and a key base component. The display component mainly includes protective glass, display screen, outer shell, adapter plate and pressure rod (including limit slot); the key base component includes a base (including guide slot), compression spring, key spring and key board. The display screen material can be OLED display screen, LCD screen or MiniLED screen.

[0047] The stroke length of the programmable display button is 2mm~3mm, and the pressing force of the button is 4N~5N. The pressing trigger force can also be adjusted by adjusting the winding ratio of the compression spring according to different usage scenarios;

[0048] The programmable display buttons can display text (Chinese characters, English or numbers). The text size and content can be set through the serial port connected to the computer software. The definition of the trigger command word corresponding to each button pressed can be edited independently and can be edited synchronously with the text displayed;

[0049] The layout of the buttons on the programmable display keyboard module 2 can be 3 rows and 5 columns, and the number of buttons can also be adjusted according to the allowable size of its installation space, that is, the number of rows and columns can be increased or shortened.

[0050] The module is powered by DC 12V or 28V and communicates with the computer through the serial port to interactively display content and send commands.

[0051] It should be noted that the shells of the three modules can all be designed to be vibration-resistant, sealed and waterproof, and anti-electromagnetic radiation, and the object is sealed by a waterproof silicone strip + aluminum alloy base plate + screw assembly.

[0052] The keyboard provided in this embodiment can be specifically applied to:

[0053] 1) Used when you need to adjust the positions of the letter keyboard, numeric keyboard and programmable display keyboard;

[0054] 2) Used when you need to adjust the button display and function;
