Folding keyboard having key modules with asymmetrical connection points

摘要: A folding keyboard includes a fixed key module and one or more mobile modules. The modules are joined together by links between them. Two ends of the at asymmetric positions. can turn 180 degrees to lie against module. is capable being frontally folded, showing whole arrangement keys after unfolding, used immediately unfolded. Moreover, be relatively shrunk way compression units reduce thickness, designed triply-folded quadruply-folded structure.
