Abstract

A keyboard structure, comprising: a substrate, a scissors mechanism, and a key lid. The scissors mechanism and the substrate are connected together. The scissors mechanism has a rotational configuration formed by cross-connecting a first rod and a second rod. The first rod has a first upper end and a first lower end. The second rod has a second upper end and a second lower end such that the first lower end and the second lower end are connected with the substrate. The key lid is connected with the first upper end and the second upper end for allowing the key lid to move between a first position, wherein the key lid and the substrate are detached, and a second position. The key lid has a base and a stop block. The base is connected with the second upper end of the scissors mechanism. The stop block is kept an appropriate distance with the base. The stop block and the base are formed into a releasing space.

Claims

1. A keyboard structure, comprising:

2. The key board structure of claim 1, wherein the first lower end is pivotally and slidably connected to the substrate.

3. The keyboard structure of claim 1, wherein the key lid further comprises a flange into which the first upper end is pivotally connected.

4. The keyboard structure of claim 1, wherein the second lower end is pivotally connected to the substrate.

5. The keyboard structure of claim 1, wherein the second upper end is pivotally and slidably connected to the base.

6. The keyboard structure of claim 1, further comprising an elastic body positioned between the substrate and the key lid, moving the key lid toward the first position.

7. A keyboard structure, comprising:

8. The keyboard structure of claim 7, wherein the first lower end is pivotally and slidably connected to the substrate.

9. The keyboard structure of claim 7, wherein the key lid further comprises a flange, into which the first upper end is pivotally connected.

10. The keyboard structure of claim 7, wherein the second lower end is pivotally connected to the substrate.

11. The keyboard structure of claim 7, wherein the second upper end is pivotally and slidably connected to the base.
