The touch screen 200 has a touch area 201, and in this embodiment, a capacitive touch screen 200a is used for illustration.

It should be noted that, although the key device in this embodiment is described by combining the above-mentioned control structure 100 with the touch screen 200, the invention is not limited thereto. For example, in other embodiments not shown in the present invention, the control structure 100 of the key device can also be used alone (for example, sold) or used with other structures.

The structures of the plurality of transparent key bodies 2 are substantially the same in this embodiment, so the following first describes a single transparent key body 2 and its corresponding (or fixed) reset bracket 1, but the present invention is not limited this. For example, in other embodiments not shown in the present invention, the structure of the plurality of transparent key bodies 2 may also be different.

Specifically, the transparent key body 2 is an integrally formed one-piece structure, and the transparent key body 2 includes a pressing portion 21 and an abutting portion 22. Wherein, the pressing portion 21 has a substantially square shape, and (the outer surface of) the pressing portion 21 includes a contact surface 211 away from the abutting portion 22, an annular step surface 212 away from the contact surface 211, and a connection The contact surface 211 and an annular side surface 213 of the annular step surface 212.

For example, in other embodiments not shown in the present invention, the abutting portion 22 may also be at least one protruding structure connected to the pressing portion 21 (eg, FIGS. 7 and 8).

Furthermore, as shown in FIGS. 2 and 4 to 6, the width W22 of the abutting portion 22 is limited to be smaller than the width W21 of the pressing portion 21, so that the pressing portion 21 and the abutting portion of this embodiment The connecting portions 22 collectively constitute a stepped structure. In other words, the abutting portion having the same width as the pressing portion is not the abutting portion 22 referred to in this embodiment. In addition, the thickness W22 of the contact portion 22 is greater than the thickness W21 of the pressing portion 21 in this embodiment, but the present invention is not limited thereto.

The pressing portion 21 of the transparent key body 2 is fixed to the fixed section 12 of the reset bracket 1, and the transparent key body 2 is not in contact with other parts of the reset bracket 1 except the fixed section 12.

Wherein, the movement of the transparent key body 2 can cause the abutting portion 22 to pass through (the large opening 131 of the reset bracket 1). Furthermore, when the contact surface 211 of the transparent key body 2 stops being pressed, the elastic section 11 will release the resilience force, thereby driving the transparent key body 2 to the initial position.

The frame 3 is formed with a plurality of perforations 31, and each transparent key body 2 and the corresponding reset bracket 1 pass through one of the perforations 31. Wherein, the setting sections 13 of the multiple reset brackets 1 are placed on the touch screen 200 (such as the housing 203) outside the touch area 201 in this embodiment, and the frame 3 and touch The control screen 200 clamps the setting section 13 of each reset bracket 1, but the present invention is not limited to this.

In this embodiment, the part of the touch area 201 facing each transparent key body 2 (the abutment portion 22) can be used to display an image 202; that is, when the touch When any image 202 in the area 201 is touched, the touch screen 200 can run a corresponding program or display multiple associated secondary images (not shown).

Furthermore, any image 202 of the touch area 201 can be seen by the contact surface 211 of the corresponding transparent key body 2. It should be additionally noted that, in order to effectively expand the viewing angle range of the image 202 seen from the transparent key body 2, the contact surface 211 is a concave arc surface in this embodiment, so that The pressing portion 21 can have a concave lens function.

Furthermore, in this embodiment, the transparent key body 2 has an optical function through the structural design of the contact surface 211; that is, the light reflected by the image 202 and penetrates into the transparent key body 2 , It will diverge when passing through the contact surface 211, so that the user can see the image 202 in a larger angle range. Among them, in order to enable the contact surface 211 of the transparent key body 2 to be suitable for pressing and optical functions, the central angle α211 of the contact surface 211 of this embodiment on any section parallel to the displacement direction S is preferably Not more than 15 degrees, but the present invention is not limited to this.

As shown in FIG. 2, FIG. 5, and FIG. 6, the contact surface 211 of any one of the transparent key bodies 2 can be pressed, so that the abutting portion 22 contacts the corresponding image 202. Wherein, when the user presses the contact surface 211 of the transparent key body 2, the resilience stored in the elastic section 11 of the reset bracket 1 and the abutment between the abutment portion 22 and the image 202 can be shared Provides a sense of feedback to the user, so that the user can manipulate the key device with limited concentration, and the user can learn the image through the feedback provided by the transparent key body 2 and the reset bracket 1 202 has been touched by the transparent key body 2.

Furthermore, in any of the transparent key bodies 2, the contact portion 22 has a contact surface 221 facing the corresponding image 202 for abutting against the image when the contact surface 211 is pressed. 202. Wherein, the touch pressure surface 221 is planar in this embodiment, so that the contact between the touch pressure surface 221 and the above-mentioned image 202 facilitates the triggering of a corresponding program on the capacitive touch screen 200a Or display multiple associated secondary images (not shown).

It should be additionally noted that the triggering of the touch screen 200 is implemented by the transparent key body 2 in this embodiment; that is, the touch screen is triggered by other methods or components (such as resetting the bracket 1) Any key device of 200 is not the key device referred to in this embodiment. Furthermore, in this embodiment, each reset bracket 1 does not touch the touch area 201 of the touch screen 200, so as to prevent the reset bracket 1 from affecting the operation of the transparent key body 2, so any touch The reset bracket to the touch area is not the reset bracket 1 referred to in this embodiment.

From another perspective, it is assumed that the transparent key body does not form an abutting portion, but the reset bracket is further formed with at least one cylindrical contact portion on the inner side of its elastic section, which is used to abut the contact control area. In the above hypothetical case, the touch screen is only abutted by the soft contact part, which is difficult to provide the feedback like this embodiment, and based on the above-mentioned contact part can only abut on the outer part of the image , This may cause the image to fail to be triggered. Accordingly, the key device of this embodiment is a structure that excludes the aforementioned hypothetical cases.

This embodiment is similar to the first embodiment described above, so the similarities of the two embodiments will not be described again, and the differences of this embodiment compared with the first embodiment described above are roughly described as follows:

In this embodiment, the touch screen 200 is further defined as a resistive touch screen 200b, and the resistive operation mechanism adopted by the touch screen 200 is different from the capacitive touch screen in the first embodiment. Therefore, the transparent key body 2 of this embodiment is adjusted to be more suitable for the structure of the resistive touch screen 200b.

Specifically, in any transparent key body 2, the contact pressing surface 221 of the contact portion 22 is a concave arc surface, so that the contact portion 22 can function as a concave lens. Wherein, the central angle α221 of the contact pressure surface 221 on any section parallel to the displacement direction S can be adjusted and changed according to design requirements, and the central angle α221 of the contact pressure surface 221 is in this embodiment It is not more than 15 degrees to illustrate, but the present invention is not limited to this.

To put it another way, because the touch screen that the transparent key body 2 needs to abut is a resistive type, the contact surface 221 of the abutment portion 22 does not need to be flat. Accordingly, by forming the contact surface 221 of the contact portion 22 into a concave shape, the viewing angle range of the image 202 viewed from the transparent key body 2 can be effectively expanded.
