Description

Keyboard component

The novel creation is related to a keyboard assembly, and in particular to a keyboard assembly in which a button assembly is detachable.

Because notebook computers have the advantages of being portable and capable of computing and processing, they are widely favored by consumers. Generally speaking, the notebook computer can be mainly divided into two parts: a display screen and a body, wherein the display screen and the body are pivotally connected to each other and can be relatively rotated, and the keyboard body is provided with a keyboard component for the user to operate through the keyboard component. Notebook computer.

The existing keyboard assembly fixes a plurality of button assemblies on a circuit board. When the user presses any of the button assemblies, it generates corresponding electrical signals and transmits them to the controller in the body through the circuit board to perform specific Features. For example, a button equipped with a mechanical shaft switch is generally used to solder a mechanical shaft switch to a circuit board, so that the user cannot easily separate the mechanical shaft switch from the circuit board. The common shaft of the mechanical shaft switch can be roughly divided into a black shaft, a white shaft, a tea shaft, a red shaft and a green shaft. If the button assembly adopts a mechanical shaft switch whose shaft is a black shaft, and is welded to the circuit board, The user cannot replace the mechanical shaft switch in the button assembly according to individual needs, for example, the mechanical shaft switch such as the white shaft, the tea shaft, the red shaft or the green shaft.

The novel creation provides a keyboard assembly in which the button assembly is detachable so that the user can replace different types of mechanical shaft switches according to individual needs.

The keyboard component of the novel creation is suitable for electronic devices. The keyboard assembly includes a base, a circuit board, and at least one button assembly. The base has at least a first perforation. The circuit board is detachably fixed to the base, wherein the circuit board and the base are electrically connected to each other, and the circuit board has at least one second through hole corresponding to the first through hole. The button assembly is detachably fixed to the base and located in the first through hole and the second through hole. The button assembly includes an adapter, a switching element, and a keycap. The adapter is detachably fixed to the base and electrically connected to the base. The switching element is detachably fixed to the adapter and electrically connected to the adapter. The keycap is detachably fixed to the switching element, and the switching element is located between the keycap and the adapter.

Based on the above, the keyboard assembly of the present invention has a button assembly detachably fixed to the base and electrically connected to the circuit board through the base. Therefore, the user can disassemble the button assembly from the base and replace the switch element (ie, the mechanical axis switch) in the button assembly according to individual needs, and then, after the switch element in the button assembly is replaced, the button is pressed. The assembly is reattached to the base. In contrast, in the prior art, the button assembly is soldered to the circuit board, and the user cannot easily separate the button assembly from the circuit board. Compared with this, the keyboard component of the new creation greatly improves the use of the keyboard assembly. Flexibility and convenience.
