Keys with noise reduction effect and its keyboard

Abstract

The invention discloses a key having a denoising effect. The key comprises a bottom plate, a key cap, a support device, buffer pieces and a balancing rod, wherein the bottom plate is provided with T-shaped hooks, the balancing rod is provided with an intermediate segment rod part and straight rod parts, the support device is movably connected between the bottom plate and the key cap, a T-shaped clamping groove and a slot are formed in the buffer piece, and the T-shaped clamping groove and the T-shaped hook are detachably buckled and connected so that the buffer piece is fixed on the bottom plate. The intermediate segment rod part is pivoted with the key cap, and the straight rod part is formed by extending one end of the intermediate segment rod part to the slot and is movably inserted into the slot. When the key cap upwards and downwards moves relative to the bottom plate, the intermediate segment rod part pivots relative to the key cap, the straight rod part upwards and downwards swings in the slot, so that the balancing rod moves with the key cap. The material of the buffer piece is softer than the material of the bottom plate, and the collision sound given out from the straightrod part swinging in the slot is reduced.

Description

technical field [0001] The invention relates to a key and its keyboard, in particular to a key with noise reduction effect and its keyboard. Background technique [0002] Generally speaking, in traditional keyboard design, when pressing a key, in order to ensure that the key switch is triggered and to obtain a good key lifting feel, a balance bar is usually provided at the bottom of the keycap of the longer key (also known as the multiple key) , in this design, the horizontal bar in the middle of the balance bar is fixed at the bottom of the keycap, and the bent bars at both ends of the balance bar are extended and hooked into the hole structure of the bottom plate support, so that when the key is pressed, The balance bar can evenly transmit the pressing force to the entire key, so that the key cap of the key can be kept horizontal and move up and down smoothly, so as to achieve a good pressing touch and the purpose of triggering the key switch. [0003] However, as can be ...

Problems solved by technology

[0003] However, as can be seen from the above, since the connection between the balance bar and the bottom plate is designed with a shaft-hole fit in which the bent bar is hooked into the hole structure, and the bent bar and the hole structure are usually clearance fit for assembly, Therefore, when the button is pressed, the bent rod will collide with the hole structure, and the bending contact surface between the bent rod and the hole structure will cause considerable noise when the bent rod and the hole structure collide, And then cause quite inconvenient operation experience when the user presses the button
