Technical Field
The invention relates to a keyboard device.
Background
In terms of the current usage habit of personal computers, keyboard devices are one of the indispensable input devices for inputting characters or numbers. Moreover, for consumer-grade electronic products in daily life or large processing equipment used in industry, a keyboard device is required to be installed as an input device for operating the electronic products and the processing equipment.
Generally, a key of a conventional keyboard device is designed to be pressed by a reset member (such as a rubber dome) and a linkage structure (such as a scissor mechanism) arranged between a key cap and a base plate, and when the key cap is pressed by a user, the reset member provides elastic restoring force to the key cap so as to drive the key cap to restore to a position before pressing along with the movement of a support structure.
For the current notebook computer, the trend is to reduce the weight and the thickness, so the keyboard structure matched with the notebook computer must be improved in the directions of reducing the overall vertical height of the keys and simplifying the mechanism in order to meet the requirement, and the change direction and the market demand of the current electronic device are met. However, the existing scissor-type supporting structure, in combination with the design of the rubber elastic body, occupies a certain vertical height, so that a certain height space must be reserved for the keyboard of the notebook computer to facilitate installation, and the thickness of the notebook computer as a whole cannot be reduced.
Therefore, how to provide a keyboard device capable of solving the above problems is one of the problems that the industry needs to invest in research and development resources to solve.

At least one of the plurality of keys comprises a keycap, two connecting rods and two magnetic attracting pieces. The keycap is located above the bottom plate. The connecting rod is connected between the base plate and the keycap and configured to guide the keycap to move towards and away from the base plate. The two magnetic attracting pieces are respectively and rotatably connected with the two connecting rods and are configured to attract each other. When the two magnetic attraction pieces lean against each other, the keycap is positioned at the highest position relative to the bottom plate. When the keycap moves from the highest position to the bottom plate, the two magnetic attraction pieces are separated.
In one or more embodiments of the present invention, one of the two magnetic parts includes a main body, a connecting portion and a magnetic part. The main body portion is rotatably connected to the corresponding link via the connecting portion. The magnetic part is connected with the main body part.

In one or more embodiments of the present invention, the magnetic attraction portion is a magnet or includes a ferromagnetic material.
In one or more embodiments of the present invention, the magnetic attraction portion is a magnet. The bottom plate is provided with a broken hole. When the keycap is located at the lowest position relative to the bottom plate, the orthographic projection of the magnetic part projected onto the bottom plate covers the broken hole.
In one or more embodiments of the present invention, each link has a lower connecting shaft and an upper connecting shaft. The lower connecting shaft and the upper connecting shaft are respectively connected to the base plate and the keycap. The connecting rods are horizontally and symmetrically arranged.
In one or more embodiments of the present invention, the links each have a substantially U-shape. Each connecting rod comprises a first supporting arm and two second supporting arms. The first arm is connected in parallel to the upper connecting shaft. Each second support arm is respectively connected between the first support arm and the lower connecting shaft and respectively extends out from the two tail ends of the first support arm.
In one or more embodiments of the present invention, the distance between the lower connecting shafts is smaller than the distance between the upper connecting shafts. The two magnetic suction pieces extend oppositely.
In one or more embodiments of the present invention, at least one of the lower connecting shafts is pivotally connected to the base plate. At least one of the upper engagement shafts is slidably engaged with the keycap.
In summary, the keyboard apparatus of the present invention uses the two connecting rods to guide the keycap to move toward and away from the bottom plate, and uses the two magnetic attraction pieces respectively rotatably connected to the two connecting rods to attract each other, so as to achieve the purpose of resetting the keycap when the keycap is not pressed. The magnetic part can replace the existing rubber dome, thereby effectively shortening the stroke of the keycap and being beneficial to thinning the keyboard device.
