Abstract

The invention is about a key. The key comprises a circuit board, a base plate arranged on the circuit board, a key cap, an optical receiver and an optical emitter which are arranged on the circuit board and mutually opposite, a base arranged on the circuit board, an upper cover arranged on the base, a first elastic part penetrating through the upper cover and the base, a support device, and a second elastic part fixed on the base and provided with a flexible rod; the support device is movably connected with the key cap and the bottom plate is provided with a sheet structure; when the key is pressed, the sheet structure blocks light path transmission between the optical emitter and the optical receiver so as to produce a trigger signal; when the key cap is pressed so that the flexible rod is downward bent and deformed along with the sheet structure and then crosses the sheet structure the flexible rod is released and upward moves to impact the upper cover, thereby making a noise. The key provided by the invention can provide key operation feeling with consistent key trigger and pressing hand-feeling feedback time difference when the user presses the key cap.

Description

technical field [0001] The present invention relates to a button, in particular to a flexible rod that uses a sheet structure of a support device to press against an elastic member to provide a pressing feel and block the optical path transmission between an optical transmitter and an optical receiver to generate a trigger signal button. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, but all consumer electronic products in daily life or large-scale processing equipment used in the industry need to be equipped with key structures as input devices to operate the above-mentioned electronic products and processing equipment. [0003] In practical applications, in order to effectively improve the accuracy of button triggering and solve the problems of easy wear and tear of switch elements and complicated welding manufa...

Problems solved by technology

[0004] However, in the actual application of the button adopting the above-mentioned optical trigger design and pressing feel feedback design at the same time, it will be affected by the different positions of the optical trigger element and the rib configuration, resulting in a time difference between the button trigger and the pressing feel feedback (usually using the button trigger The time point is later than the design of the pressing feel feedback time point) will be different according to the position of the keycap being pressed, so that when the user presses the button, it will bring the pressing operation feeling that the time difference between the key trigger and the pressing feel feedback time difference is inconsistent
