[0020] As shown in FIGS. 4 to 6, the keyboard unit 121 includes at least one button 1211. When the fixing unit 122 fixes the keyboard unit 121 to the mobile device 11, the button 1211 is pressed and contacts the touch display unit 111, so that the mobile device 11 generates a corresponding touch signal. In this embodiment, the button 1211 may be an elastic structure, and the button 1211 may be made of conductive rubber so as to be used in accordance with the touch display unit 111 adopting a capacitive design. However, the present invention is not limited to this embodiment. For example, in another embodiment, the button may be made of non-conductive plastic so as to be pressed and used in accordance with the touch display unit adopting a resistive design.
[0021] Further, the keyboard unit 121 further includes an upper cover 1212, a lower cover 1213, and at least one connecting member 1214 connecting the upper cover 1212 and the lower cover 1213. In this embodiment, for example, the connecting member 1214 may be a screw, but the present invention is not limited to this embodiment.
[0022] Also, as shown in FIGS. 4 to 6, at least one upper opening H1 is formed in the upper cover 1212, at least one lower opening H2 is formed in the lower cover 1213, the periphery of the button 1211 is located between the upper cover 1212 and the lower cover 1213, and is clamped by the upper cover 1212 and the lower cover 1213. The upper structure of the button 1211 is exposed outside the upper cover 1212 through the corresponding upper opening H1. When the upper structure of the button 1211 is pressed, the lower structure of the button 1211 moves in conjunction, penetrates the corresponding lower opening H2, and contacts the touch display unit 111. On the other hand, when the upper structure of the button 1211 is released without being pressed, the lower structure of the button 1211 returns to its original position elastically, does not penetrate the corresponding lower opening H2, and separates from the touch display unit 111. That is, when the upper structure of the button 1211 is not pressed, the lower structure of the button 1211 separates from the touch display unit 111 without penetrating the corresponding lower opening H2.
[0023] Preferably, in this embodiment, as shown in FIGS. 1, 2, and 4, different patterns or characters may be formed on different buttons 1211 by methods such as spraying, printing, laser engraving, etc. to make them distinguishable, but the present invention is not limited to this embodiment. For example, in another embodiment, different buttons may be designed with different outer shapes, and patterns and characters may not be formed either.
[0024] Also, in this embodiment, as shown in FIGS. 2, 3, and 6, the fixing part 122 includes a frame structure 1221. In order to prevent the relative movement between the keyboard part 121 and the mobile device 11, the frame structure 1221 at least partially covers the periphery of the keyboard part 121 and the periphery of the mobile device 11. The overall size of the frame structure 1221 is substantially the same as the overall size of the mobile device 11. For example, it may be in the form of a protective frame of the mobile device 11, but the present invention is not limited to this embodiment. For example, in another embodiment, the fixing part may be an adhesive, a clip, or a tape.
[0025] Preferably, as shown in FIGS. 2, 4, and 6, at least one first engaging member E1 is formed on the frame structure 1221, and at least one second engaging member E2 that engages with at least one first engaging member E1 is formed on the periphery of the keyboard part 121. Due to the engagement between the first engaging member E1 and the second engaging member E2, it is possible to effectively avoid the frame structure 1221 accidentally detaching from the periphery of the keyboard part 121, thus avoiding the accidental separation of the keyboard part 121 and the mobile device 11. In this embodiment, for example, the first engaging member E1 may be an engaging hook formed on the frame structure 1221, and the second engaging member E2 may be an engaging platform formed on the periphery of the lower cover 1213 of the keyboard part 121, but the present invention is not limited to this embodiment. For example, in another embodiment, the first engaging member and the second engaging member may be an engaging convex part and an engaging concave part respectively.
[0026] Referring to FIGS. 7 to 9, FIG. 7 is a schematic exploded view of the elements of the electronic touch system 1' of the second embodiment of the present invention, FIG. 8 is a schematic exploded view of the partial structural elements of the electronic touch system 1' of the second embodiment of the present invention, and FIG. 9 is a schematic cross-sectional view of the partial structure of the electronic touch system 1' of the second embodiment of the present invention. As shown in FIGS. 7 to 9, the difference from the first embodiment is that the fixing portion 122' of the keyboard device 12' of the electronic touch system 1' may include a frame structure 1221' that at least partially covers the periphery of the keyboard portion 121' and the periphery of the mobile device 11' in order to prevent relative movement between the keyboard portion 121' and the mobile device 11'. Also, in order to be able to attach and mount the keyboard portion 121' to the touch display portion 111' of the mobile device 11', it further has an adhesive layer 1222' attached to the side of the lower cover 1213' of the keyboard portion 121' of the keyboard device 12' away from the upper cover 1212'. At least one retraction opening H3' is formed in the adhesive layer 1222'. Thus, the lower structure of the button 1211' can pass through the corresponding lower opening H2' on the lower cover 1213' and the corresponding retraction opening H3' on the adhesive layer 1222' to contact the touch display portion 111'. Also, as shown in FIGS. 7 to 9, the quantity and arrangement of the buttons 1211' of the keyboard portion 121' of the second embodiment may be different from those of the first embodiment, and the keyboard portion 121' of the second embodiment may not include a connecting member for connecting the upper cover 1212' and the lower cover 1213'. The other configurations of the second embodiment are the same as those of the first embodiment and also have various variations, which are omitted here for the sake of brevity.
