In the description of the specification, in order to give the reader a more complete understanding of the present invention, many specific details and implementation examples are provided; however, these specific details and implementation examples should not be regarded as limitations of the present invention. In addition, well-known steps or elements are not described in detail to avoid unnecessary limitations of the present invention.

[0026] Figure 1A is a first perspective stereogram of a keyboard 1 according to an embodiment of the present invention; Figure 1B yes Figure 1A A second perspective stereoscopic image of the keyboard 1 .

[0027] Please refer to Figure 1A and Figure 1B The keyboard 1 may include a plurality of key modules 10 and a main circuit board 11. The key modules 10 may be electrically connected to the main circuit board 11. In one embodiment, the keyboard 1 may be an input device of a notebook computer, and the main circuit board 11 may be connected to a conversion board BD via a flexible connection line F, and then electrically connected to a system circuit board of the notebook computer via exposed pads P of the conversion board BD.

[0028] Figure 2 yes Figure 1A An exploded view of the key module 10 in the keyboard 1 is shown.

[0029] Please refer to Figure 2 The key module 10 may include a key cap 100, a modular circuit board 101, a movable member 102 and a bottom plate 103. The movable member 102 is located between the key cap 100 and the modular circuit board 101. The modular circuit board 101 may be located above the bottom plate 103, and the modular circuit board 101 and the bottom plate 103 may be fixed to each other by an adhesive layer AH. In addition, a protective sheet PS may be provided at the bottom of the key module 10 to protect the internal structure of the key module 10.

[0030] When the keycap 100 is pressed, the movable member 102 can drive the keycap 100 to move along the Y axis. In one embodiment, the movable member 102 may include a connecting structure 1020 and an elastic member 1021. The connecting structure 1020 is disposed between the keycap 100 and the base plate 103. The elastic member 1021 is disposed between the keycap 100 and the modular circuit board 101, and the elastic member 1021 has a conductive column that can be electrically conductive. The modular circuit board 101 may have a conductive point CP and a circuit, and the conductive point CP may correspond to the conductive column inside the elastic member 1021. When the keycap 100 is subjected to a pressing force, the elastic member 1021 will deform, so that the conductive column inside the elastic member 1021 can be conductive with the conductive point CP of the modular circuit board 101, thereby generating a trigger signal. Once the pressing force on the keycap 100 disappears, the elastic member 1021 can exert a restoring force on the keycap 100 , and the keycap 100 can be restored to its original position under the guidance of the connecting structure 1020 .

[0031] Figure 3 yes Figure 2 A top view of a modular circuit board 101 in a key module 10; Figure 4 Draw Figure 2 A schematic diagram of a key module 10 assembled on a keyboard 1; Figure 5 Draw Figure 4 A partial enlarged view of the keyboard 1 after the key module 10 is assembled.

[0032] Please refer to Figure 3 and Figure 4 The modular circuit board 101 and the main circuit board 11 are both rigid structures, such as a printed circuit board assembly (PCBA). Therefore, other electronic components, such as a diode D, a light-emitting diode L, etc., may also be provided on the modular circuit board 101.

[0033] Please refer to Figure 3 and Figure 4 The edge of the modular circuit board 101 may be provided with a plurality of connection holes H1 and at least one alignment hole H2. The shape of the alignment hole H2 may be different from that of the connection hole H1 so as to be distinguishable from the connection hole H1. Figure 4 As shown, the main circuit board 11 may have an accommodation area AA for accommodating the keyboard module 10, and a positioning hole 11H near the accommodation area AA that can be combined with a bent hook (not shown) of the bottom plate 103 of the keyboard module 10. In addition, the main circuit board 11 may also have a mark symbol (not shown) for alignment. The alignment hole H2 of the modular circuit board 101 can be aligned with the mark symbol of the main circuit board 11 to achieve the alignment of the keyboard module 10, so that the bottom plate 103 of the keyboard module 10 can be engaged with the main circuit board 11 through the bent hook and the positioning hole 11H, so that the keyboard module 10 is located in the accommodation area AA of the main circuit board 11.

[0034] The key module 10 can be electrically connected to the main circuit board 11 via the modular circuit board 101. Figure 4 and Figure 5 When the keyboard module 10 is located in the accommodation area AA of the main circuit board 11, a welding area SD can be formed between the connecting holes H1 of the modular circuit board 101 and the main circuit board 11. Specifically, the main circuit board 11 can have bare copper, and the position of the bare copper corresponds to each connecting hole H1 of the modular circuit board 101. These connecting holes H1 of the modular circuit board 101 can be correspondingly welded to the bare copper of the main circuit board 11, so that the modular circuit board 101 and the main circuit board 11 are electrically connected.

[0035] Since these connecting holes H1 of the modular circuit board 101 are connected to the main circuit board 11 by welding, if one of the key modules 10 fails, the failed key module 10 can be removed from the keyboard 1 for repair, or replaced with another key module 10 according to the aforementioned assembly method, which can greatly reduce the cost of repair and increase the convenience of repair.

The elastic member 3021 is disposed between the keycap 300 and the trigger circuit layer 305. When the keycap 300 is subjected to a pressing force, the elastic member 3021 will deform, so that the elastic member 3021 presses and conducts the upper and lower circuits of the trigger circuit layer 305, thereby generating a trigger signal. Once the pressing force on the keycap 300 disappears, the elastic member 3021 can exert a restoring force on the keycap 300, and the keycap 300 can be reset by the guidance of the connecting structure 3020.

The key structure KS3 is disposed above the modular circuit board 501 , and the key structure KS3 and the modular circuit board 501 are disposed in the housing 504 .

[0062] The modular circuit board 501 and the main circuit board 51 are both rigid structures, such as a printed circuit board assembly (PCBA). In this embodiment, the housing 504 is not covered under the modular circuit board 501, so the bottom of the key module 50 is the modular circuit board 501.
