Abstract

The invention provides a metal induction button. The metal induction button comprises a metal panel, mucilage glue, a circuit board, a metal plate liner plate and a bottom box, wherein the metal panelis connected with the metal plate liner plate through mucilage glue; the mucilage glue and the circuit board are embedded into the metal plate liner plate; a rivet is arranged on the metal plate liner plate, and is connected with the bottom box through a screw; the circuit board is equipped with a bonding pad; after a human body presses the surface of the metal panel, the surface of the metal panel is deformed to rotate to the bonding pad of the circuit board; according to the formula C= epsilon0 epsilonr A / d, a capacitance value changes when a distance d changes; the circuit board is connected with a control module; and the thickness of the metal panel is smaller than 1 mm. The metal induction button adopts metal surface deformation to cause capacitance changes, so that mechanism transmission is reduced, the service life is longer, contact is required, and disorderly operation of elevator buttons is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of elevator buttons, in particular to a metal induction button. Background technique [0002] With the progress of the society and the continuous improvement of the industrial level, the design of the elevator buttons not only realizes its functions, but also puts forward some higher requirements. Such as humanization: the appearance of the mechanism should be beautiful and generous, easy for users to identify, and feel comfortable when operating. Diversification: Different places should have buttons in line with their usage environment, etc. [0003] At present, most elevators use openings to install mechanical buttons, which have limitations in appearance and travel. In order to change the limitations in appearance and travel, it is necessary to design buttons that better meet people's requirements. Contents of the invention [0004] In order to overcome the problems of unattractive holes on the surfac...
