[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of a keyboard that allows for the replacement of multiple decorative parts and product function modules. It includes a main shell 1, which is a keyboard shell as described in the prior art. The main shell 1 has keycaps on its surface and corresponding internal key switches. A power supply port is located at its rear end. A main circuit board 9 is located on the inner sidewall of the main shell 1. A standardized electrical connection interface 8 is located at the bottom of the main circuit board 9. Power can be supplied to the main circuit board 9 through the power supply port at the rear end of the main shell 1, and the main circuit board 9 also supplies power to the standardized electrical connection interface 8, enabling data transmission and power delivery through the standardized electrical connection interface 8. An expansion component 2 is in contact with the outer sidewall of the main shell 1. The shape of the expansion component 2 matches the shape of the main shell 1. A side PCB board 3 is detachably mounted on the inner sidewall of the expansion component 2. A module-side electrical connection interface 7 is located on the right side surface of the side PCB board 3. The standardized electrical connection interface... The port 8 is electrically connected to the module side electrical connection interface 7. The front surface of the side PCB board 3 is provided with a circuit function module 4, and a filler is provided between the two to avoid direct contact between the circuit function module 4 and the side PCB board 3. The surface of the expansion component 2 is provided with a mounting groove. The outer wall of the circuit function module 4 contacts the inner wall of the mounting groove of the expansion component 2. The contact between the two allows the circuit function module 4 to be positioned and installed. The bottom end of the circuit function module 4 is provided with a sliding groove. The inner wall of the sliding groove at the bottom end of the circuit function module 4 is provided with a physical button 5. The end of the physical button 5 is electrically connected to the side PCB board 3. The circuit function module 4 is existing technology. It has an LED lighting effect module and a touch screen module. By providing the physical button 5, the physical button 5 has different actual functions for different circuit function modules 4. It works in conjunction with the computer driver to achieve the integration of hardware and software.

[0031] Reference Figure 2 and Figure 3 The circuit function module 4 has positioning grooves on all four sides, and the inner wall of the positioning groove of the circuit function module 4 contacts the positioning screw 6. The expansion component 2 has positioning grooves at all four corners, and the outer wall of the positioning screw 6 contacts the inner wall of the positioning groove of the expansion component 2. The main shell 1 has internal thread grooves at all four corners of the side wall, and the positioning screw 6 is threaded to the inner wall of the internal thread groove at the four corners of the main shell 1. The positioning screw 6 passes through the circuit function module 4 and the expansion component 2 and is threaded to the side wall of the main shell 1, so that the circuit function module 4 can be fixed inside the expansion component 2, thereby realizing the modular installation of the electronic control function. The installation method of the positioning screw 6 can be adjusted to magnetic suction and snap-on installation according to the actual situation.

[0032] Working principle: In terms of basic power supply and connection, the power supply port at the rear of the main shell 1 supplies power to the internal main circuit board 9. The main circuit board 9 transmits power to the standardized electrical connection interface 8. At the same time, the standardized electrical connection interface 8 also undertakes the data transmission function. When the expansion component 2 contacts the outer side wall of the main shell 1, the module-side electrical connection interface 7 on the side PCB board 3 on the inner side of the expansion component 2 is electrically connected to the standardized electrical connection interface 8 of the main circuit board 9, realizing the transmission of power and data between the main shell 1 and the expansion component 2.

[0033] Regarding the operation and replacement of circuit function module 4: Circuit function module 4 (such as LED lighting effect module, touch screen module, etc.) is installed in the mounting slot of expansion component 2, with its outer wall contacting the inner wall of the mounting slot for positioning. During installation, the positioning screw 6 passes through the positioning slots around the circuit function module 4 and the positioning slots at the four corners of the expansion component 2, and is threadedly connected to the internal threaded slots at the four corners of the side wall of the main shell 1 (magnetic or snap-on installation can also be used), fixing the circuit function module 4 inside the expansion component 2. At this time, the circuit function module 4 establishes an electrical connection with the main circuit board 9 through the side PCB board 3, and the end of the physical button 5 at its bottom is electrically connected to the side PCB board 3. When in use, the physical button 5 performs the corresponding function according to the characteristics of different circuit function modules 4, matching and linking with the computer driver to achieve hardware and software integration, such as controlling LED lighting effects and operating the touch screen. If a function module needs to be replaced, simply remove the positioning screw 6, remove the old module and replace it with the new module, and then re-fix it.

[0034] Example 2:

[0035] Reference Figure 3 The inner wall of the positioning groove of the expansion component 2 can also be detachably installed with a piece of decorative material 10. The shape of the piece of decorative material 10 fits the inner wall of the mounting groove of the expansion component 2, and its surface is decorated with patterns. It can be adjusted according to the actual product to achieve an aesthetically pleasing installation. Similarly, the piece of decorative material 10 can be connected and fixed to the expansion component 2 and the main shell 1 by passing through the positioning screw 6.

[0036] Working principle: The shape of the decorative piece 10 fits the inner wall of the positioning groove of the expansion component 2, and the surface can be customized with patterns. During installation, the decorative piece 10 is placed into the positioning groove of the expansion component 2, and the positioning screw 6 (or magnetic, snap-fit, etc.) passes through the decorative piece 10 and the expansion component 2, and is fixed to the main shell 1 to achieve the decorative effect. When replacing, the positioning screw 6 is removed, the old decorative piece is removed and replaced with a new decorative piece 10, and then it is re-fixed to complete the customized update of the decoration.
