A computer key with ergonomic scissor feet

Abstract

The invention relates to a computer button utilizing an ergonomics scissors foot. The computer button comprises the ergonomics scissors foot. The ergonomics scissors foot is formed by an outer frame and an inner frame hinged in the outer frame. The symmetrical inner frame comprises an inner frame front arm, an inner frame rear arm, a left inner frame connecting arm and a right inner frame connecting arm, wherein the left inner frame connecting arm and the right inner frame connecting arm are connected between the inner frame front arm and the inner frame rear arm. The outer frame comprises an outer frame front arm, an outer frame rear arm, a left outer frame connecting arm and a right outer frame connecting arm, wherein the outer frame front arm is parallel with the outer frame, and the left outer frame connecting arm and the right outer frame connecting arm are connected between the outer frame front arm and the outer frame rear arm. The front and the rear of the outer frame are asymmetrical. After assembling, the inner frame front arm and the inner frame rear arm are matched with a slide lateral clamping hook at the bottom of a button cap and a slide lateral clamp hook on a base plate of the button in one-to-one correspondence, the outer frame rear arm is correspondingly clamped to two corresponding fixed clamp seats on the button cap, and the outer frame front arm is correspondingly clamped to two corresponding fixed clamp seats on the button base plate. Accordingly, the button is stable and not shaken when being pressed by fingers, comfortableness of the button is improved, and the button accords with ergonomics.

Description

technical field [0001] The invention relates to the technical field of computer keys, in particular to a computer key using ergonomic scissor feet for notebook computers or desktop computers. Background technique [0002] With the development of the information industry, computers have been increasingly widely used. Whether it is a notebook computer or a desktop computer, the computer key is inseparable from the application. The existing notebook keys and some desktop computers such as the thin and light keys used by the Apple Computer all adopt the structure of scissor legs. The existing scissor legs are all formed by the inner frame It is hinged with the outer frame. When installing, it is necessary to open a slot above or below the shaft hole so that the shaft can be snapped into the shaft hole; there are four corresponding points on the bottom of the key cap and the bottom plate of the key corresponding to the inner frame and the outer frame. The four pins; the front an...

Problems solved by technology

However, in the process of pressing the keys with fingers, people find that the existing scissors keys have the following defects: first, when the existing scissors inner frame and outer frame are installed, it is necessary to open a slot above or below the shaft hole. It is convenient for installation, but it reduces the assembly strength. In the case of falling or impacting the keyboard, the inner frame and outer frame may fall off from the through groove; second, the existing inner frame structure is too complicated, and it needs to be Four pins are arranged on the inner frame, and four corresponding points are also required to be respectively arranged on the bottom surface of the button cap and the button bottom plate. This structure is complicated and is not convenient for large-scale production and cost saving; The length of the front and rear arms of the foot frame is equal, and the front and rear structures are symmetrical, so that the support strength of the key cap is the same. However, when the finger presses the key, the fingertip usually touches the front of the key first, and then the main focus of the finger falls on the key. This makes the force on the rear arm of the outer frame greater than the forearm of the outer frame, so that the keys are unevenly stressed and easy to shake when the fingers are pressed, which affects the comfort and the strength of the scissor feet in the keys, which is not ergonomic
