[0032] As shown in Figures 1 to 5, this embodiment of the invention provides a modular keyboard, including a main keyboard 1 and a keyboard combination function module 2. In practical applications, the main keyboard 1 can adopt a common standard keyboard layout, such as a 104-key or 87-key keyboard, which has basic input functions. The keyboard combination function module 2 is detachably mounted on the side of the main keyboard 1 and is electrically connected to the main keyboard 1. The keyboard combination function module 2 includes an auxiliary keyboard 21 and a touch screen 22. The auxiliary keyboard 21 includes a substrate 211 and a keypad 212. The substrate 211 has a groove 2113, and the keypad 212 is movably mounted in the groove 2113. The touch screen 22 is located on the bottom surface of the groove 2113. The touch screen 22 can be connected to the control circuit of the substrate 211 via a flexible PCB board or a wired connection.

[0033] The substrate 211 serves as the main support, and the depth of its groove 2113 is typically designed to be slightly greater than the thickness of the button panel 212 to ensure that the button panel 212 moves smoothly within the groove 2113 without jamming. The substrate 211 can be made of PC+ABS alloy material, combining strength and toughness. The bottom surface of the groove 2113 is precision-milled using CNC to ensure a smooth surface finish for the touchscreen 22. The touchscreen 22 is fully bonded to the bottom surface of the groove 2113 using optical adhesive (OCA). A 5mm non-display area is reserved at the edge of the touchscreen 22 for laying electrical connection lines. To prevent the button panel 212 from squeezing the touchscreen 22 when rotating, 0.3mm thick silicone cushioning pads are attached to the four corners of the bottom surface of the groove 2113.

[0034] The signal transmission principle of the touch screen 22 is as follows: when the touch screen 22 senses a signal, it transmits the sensed signal to the control circuit of the substrate 211 through the flexible PCB board or wired cable, and then transmits it to the control chip of the main keyboard 1.

[0035] The auxiliary keyboard 21 serves as a shortcut key input area, while the keypad 212 is equipped with commonly used function keys such as copy, paste, and undo. When users need to edit text, they can quickly perform related operations by pressing the keys on the keypad 212; while when they need to perform operations such as image zooming or page scrolling, they can directly perform gesture operations such as sliding and pinching on the touchscreen 22 on the bottom surface of the recess 2113. This design allows users to complete both physical key input and touch operations within the same area, greatly improving operational efficiency.

[0036] The keyboard combination function module 2 is located on at least one side of the main keyboard 1, either the left or right side. As shown in Figure 1, the keyboard combination function module 2 is assembled on the right side of the main keyboard 1, which is a single-sided assembly mode. As shown in Figure 2, the keyboard combination function module 2 is assembled on both the left and right sides of the main keyboard 1, which is a double-sided assembly mode. The single-sided assembly mode is suitable for office environments with limited desktop space, saving approximately 40% of the horizontal occupancy area; while the double-sided assembly mode meets the extreme needs of professional users for functional expansion, significantly improving operational efficiency.

[0037] Both the left and right sides of the main keyboard 1 are provided with slots 11, which extend along the width direction of the main keyboard 1, and the length of the slots 11 is greater than or equal to half the width of the main keyboard 1. For example, if the width of the main keyboard 1 is 30cm, the length of the slots 11 can be set to 15cm or longer to ensure the stability of the keyboard combination function module 2 after connection. If the length of the slots 11 is too short, it is easier for slippage to occur after assembly. Furthermore, in order to improve the stability after assembly, the slots 11 and the locking parts 2111 form an interference fit after connection, that is, there is a certain pre-tightening force after connection. It should be noted that the length of the slots 11 cannot be equal to the width of the main keyboard 1, that is, the slots 11 cannot be set through the width direction of the main keyboard 1. The purpose of this design is to prevent the keyboard combination function module 2 from accidentally slipping off the main keyboard 1 after assembly.

[0038] The inlet end of the card slot 11 is located on the front side of the main keyboard 1. The card slot 11 includes a vertical hole portion 111 and a horizontal hole portion 112 communicating with the vertical hole portion 111. An opening 1121 is provided on the side of the horizontal hole portion 112 away from the vertical hole portion 111. The left and right sides of the substrate 211 are provided with a latching portion 2111 that engages with the card slot 11. The latching portion 2111 includes a vertical plate portion 21111 and a horizontal plate portion 21112. One side of the horizontal plate portion 21112 is fixedly connected to the substrate 211, and the side of the horizontal plate portion 21112 away from the substrate 211 is fixedly connected to the vertical plate portion 21111. During installation, the vertical plate portion 21111 of the latching part 2111 is inserted into the vertical hole portion 111 through the entrance end of the latching slot 11, and then the horizontal plate portion 21112 is inserted into the horizontal hole portion 112 through the entrance end of the latching slot 11, thereby achieving a stable connection between the keyboard combination function module 2 and the main keyboard 1; during disassembly, the operation is reversed.

[0039] As shown in Figures 3 and 4, the main keyboard 1 has multiple electrical contacts on its splicing surface, and the substrate 211 has corresponding electrical contact points 12 that are adapted to the electrical contacts. When the keyboard combination function module 2 and the main keyboard 1 are assembled and connected by the slot 11 and the snap-fit ​​part 2111, the electrical contacts and the electrical contact points 12 are in close contact, thereby realizing signal transmission, so that the auxiliary keyboard 21 and the touch screen 22 can work together with the main keyboard 1.

[0040] The rear side of the keypad 212 is rotatably connected to the base plate 211 via a rotatable assembly.

[0041] The rotatable assembly includes a rotating shaft. A rotating groove is provided on the base plate 211. Both ends of the rotating shaft are movably disposed in the holes of the base plate 211, with the portion between the two ends located in the rotating groove. A protrusion 2121 is provided on the rear side of the keypad 212. The protrusion 2121 has a shaft hole and is disposed in the rotating groove and sleeved on the rotating shaft through the shaft hole. To provide appropriate resistance and return effect when the keypad 212 rotates, the rotatable assembly also includes a damping plate and a spring. Both the damping plate and the spring are sleeved on the rotating shaft. The spring is located inside the shaft hole, and the damping plate is located outside the shaft hole and abuts against the spring. During use, the user can rotate the keypad 212 to a suitable angle according to their needs. For example, rotating the keypad 212 upwards by a certain angle makes it easier for the fingers to press the buttons. After use, the keypad 212 automatically returns to its original position under the action of the spring.

[0042] In summary, this utility model, through its detachable design, allows users to flexibly install or remove the keyboard combination function module 2 according to their own usage scenarios and needs. For example, in daily office work, only the main keyboard 1 can be used to save space, while function modules can be added for professional design or gaming operations, greatly improving the flexibility and adaptability of keyboard use. Furthermore, the keypad 212 of the auxiliary keyboard 21 in the keyboard combination function module 2 is movably disposed within the groove 2113 of the base plate 211. Combined with the touchscreen 22 on the bottom surface of the groove 2113, it achieves an organic integration of physical buttons and touch operation. Users can perform fast and accurate command input via buttons and also utilize the touchscreen 22 for diverse operations such as sliding and zooming, enriching input methods, significantly improving operational efficiency, and satisfying the operating habits of different users. In addition, the structure is compact and reasonable, effectively controlling the overall size while achieving functional expansion, thus balancing practicality and portability.
