In FIG. 1, a keyboard 100 having an auxiliary support structure includes a keyboard body 110 and two support members 112. The keyboard body 110 has an abutting surface 111. This abutting surface 111 is provided, for example, in a protrusion 1102. That is, the surface of the protrusion 1102 can serve as the abutting surface 111. The two supporting members 112 are pivotally connected to the keyboard body 110 , for example, pivoted under the protrusions 1102 . In FIG. 2, when each support member 112 is rotated by an angle θ 1 with respect to the keyboard body 110, the pivot end of each support member 112 is fixed and the other end is rotated by an angle θ 1 with respect to the protrusion portion 1102. At this time, the bearing portions 114 of the respective supporting members 112 are respectively rotated from the two sides of the protruding portion 1102 to the abutting surface 111 on the other side of the protruding portion 1102, and are opposite to the abutting surface 111 and spaced apart to form a space. A groove 113 is between the bearing portion 114 of each support member 112 and the abutting surface 111.

In FIG. 2, the protrusion 1102 of the keyboard body 110 is located at the center side of the keyboard body 110, and the two sides of the keyboard body 110 are provided with two recessed portions 1104 such that the protrusions 1102 are located between the two recessed portions 1104. When the support members 112 are rotated relative to the keyboard body 110, the ribs 1121 and the recesses 1104 of the support member 112 Separating, the shape of the rib 1121 matches the shape of the recess 1104. In FIG. 3, when the support members 112 are not opened, the ribs 1121 of the support members 112 are in close contact with the recessed portions 1104, so that the ribs 1121 are received in the corresponding recessed portions 1104. At this time, the rib 1121 of the support member 112 and the abutting surface 111 are preferably coplanar to form a rectangular keyboard.

In FIGS. 1 and 4A, the height of the rib 1121 is equal to the depth H of the groove 113, that is, the thickness of the support member 112 minus the thickness of the bottom support plate 1122 of the support member 112 is the height of the rib 1121 (or the groove). 113 depth H). In this embodiment, the rib 1121 and the bottom support plate 1122 form an L-shaped structure that cooperates with the shape of the recess 1104 (L-shaped groove) so that the rib 1121 and the bottom support plate 1122 are correspondingly received in the recess. 1104.
