Description

Combined key keyboard

Technical Field

The invention relates to the technical field of computer communication, in particular to a combined key keyboard.

Background

Computer keyboards are mainly classified into mechanical keyboards, plastic film keyboards, conductive rubber keyboards, and capacitive keyboards. The mechanical keyboard has keys in mechanical shaft structure, and the mechanical shaft is generally composed of a base, a shaft cap fixing clip, a spring, a metal support leg and a contact metal sheet. The plastic film type keyboard is mainly divided into a crater structure, a scissor structure and a palace column structure. Wherein, the key cap and the guide post integrated into one piece of volcanic vent structure, the key cap can be directly and the rubber membrane contact. One of the disadvantages is that the hand feel is not fixed. Because the keycap is contacted with the convex rubber film with elasticity, the keycap can shake when the key is pressed. And the best hand feeling can be obtained only when the keycap is contacted with the highest point of the rubber film, which needs to be realized only when the finger is dropped in the center of the keycap during input. The scissor foot structure is characterized in that the keycaps are separated from the guide columns, and the support frame with two groups of connecting rod structures is adopted between the keycaps and the rubber films. The advantage of this kind of structure is can feel the strength that comes from four angles of key cap and middle transmission, and this has just solved the inhomogeneous condition of feeling of crater structure to a certain extent. The appearance of the palace column structure aims to solve the problem that the keycap of the crater structure is easy to wear, so the keycap is separated from the guide column, and the guide column is made of brand-new high-hardness materials and is columnar. The keys of the existing computer keyboard are mutually independent, and each key is provided with a key cap or controls one key. Thus, the minimum area of each key is limited by the area of the human finger. So that the notebook computer often needs to reduce the number of keys. In the existing keyboard, each finger needs to control 4-8 keys during typing, and the keys are far apart, so that the palm and the arm need to move along with the keys when the upper row of numeric keys are knocked. The fingers are different in length, and the keys of the traditional keyboard must be linearly arranged, so that the fingers cannot work in a natural and comfortable posture, and are uncomfortable and easy to get tired. Each keycap of the traditional keyboard corresponds to a key, and the keycaps must be locked; then, when the keycap needs to be taken down for cleaning, the labor is required, and even the key is worried about to be pulled out.
