Key module with noise-reducing lifting mechanism
The patent US12046426B2 describes a key module designed for use in various electronic devices. The key module consists of a base plate, a circuit layer mounted on the base plate, and a keycap that is connected to a lifting mechanism. The lifting mechanism allows the keycap to move vertically relative to the circuit layer. Notably, the keycap features a skirt portion and a connecting portion, with the latter designed to engage with a recessed hole in the circuit layer when the keycap is pressed. The claims detail various configurations of the key module, including the physical interactions between the keycap, the circuit layer, and the lifting mechanism, which may include elastic components to enhance the tactile feedback during use.
Further claims elaborate on the structural elements of the key module, such as the presence of multiple membranes within the circuit layer, which may include perforation and interference portions. The design also incorporates an abutment element that interacts with the circuit layer, ensuring proper contact during key presses. The claims specify various configurations for the abutment element, including its material properties and geometric arrangements, which are intended to optimize the key module's performance. Overall, the patent outlines a comprehensive design aimed at improving the functionality and user experience of key modules in electronic devices.
