However, this design produces The problem is also the same as the pressing structure described above. If sufficient pressing stroke or resilience is required, the thickness of the elastic material also needs to be increased, and the pressing structure of this type abandons the design of the bridging, so the key cap itself is easy. In addition to the above structure, the Republic of China Patent No. 516058 discloses a thin keyboard structure, which is made of an elastic material, which generates a tilt and a key that provides a downward triggering pressure. A spring is provided between the shaft and the circuit switch to provide a large stroke of the keycap itself, thus producing a significant resilience, but due to the cylindrical mandrel in the pressing structure The upper key cap cannot be effectively supported, and the key cap and the substrate are also supported by the mandrel, and therefore, the key cap is also prone to tilting.

[0008] Thereby, the pressing structure of the thin keyboard of the present invention is deformed by the elastic segment to trigger the electric road plate through the pressing stroke, and the elastic segment deforms when the user feels a significant pressure drop difference. When the elastic segment returns to the initial state, the user can feel the feedback force, and the key cap can be smoothly carried on the substrate by the protruding structure of the balance segment and the first and second brackets. When the user performs the operation, the pressing pressure channel can be uniformly transmitted to the elastic segment for triggering.
