THIN KEY STRUCTURE AND PRESSABLE MODULE THEREOF

摘要

A thin key structure includes a circuit module, a frame having has a retaining portion, an elastic member disposed on the circuit module and arranged in the frame, and a pressable module having a positioning sheet and a key. The positioning sheet has an assembling portion installed on the frame, a connecting portion, and an extending portion connecting there-between. The key has a key body fixed on the connecting portion and a stopping portion extended from the key body. The key body has a concaving portion aligning the extending portion. The stopping portion is movably arranged in the retaining portion. When non-center portion of the key body is pressed, part of the stopping portion, away from the pressed portion of the key body, abuts against the corresponding retaining potion for being a fulcrum, such that the pressed portion of the key body rotates to press the elastic member.

主权项

1. A thin key structure, comprising:
a circuit module; a frame disposed on the circuit module and defined with an accommodating space, wherein the frame has a retaining portion formed on an inner surface thereof; an elastic member disposed on the circuit module and arranged in the accommodating space of the frame; and a pressable module comprising:
a positioning sheet having an assembling portion, a connecting portion, and an extending portion integrally connected between the assembling portion and the connecting portion, wherein the assembling portion is fixed on the frame, and the connecting portion and the extending portion are movable with respect to the assembling portion; anda key having a key body and a stopping portion integrally protruding from a periphery edge of the key body, wherein the key body is fixed on the connecting portion of the positioning sheet and arranged above the elastic member, the key body has a concaving portion aligning the extending portion, and the stopping portion is movably arranged in a space defined by the retaining portion; wherein when a non-center portion of the key body is pressed, part of the stopping portion away from the pressed position of the key body is abutted against the corresponding retaining portion to be at least one fulcrum, and the pressed portion of the key body rotates about the fulcrum to resiliently deform the elastic member for establishing a connection of the elastic member and the circuit module.
