The present invention relates to a structure of an input device, and in particular, to a keyboard having a water-proof and dust-proof function.
In the modern society, the use of electronic devices has become an indispensable part of the life, and necessities such as eating, clothing, living, traveling, teaching, and entertainment are correlated to electronic devices. Generally, a keyboard structure is configured in a consumer electronic device.
Electronic devices are closely correlated to people's life. A user may accidentally splash a drink or water to a surface of an electronic device during use, and the drink or water penetrates into the electronic device through gaps between keys and a housing, further causing damage to the electronic device. In addition, dusts suspending in the air or dirt on the hands may enter the electronic device from the gaps between the keys and the housing, and therefore impact operating of the electronic device.
Therefore, how to provide a keyboard having a water-proof and dust-proof function and a key structure thereof is a technical issue to be resolved by the present invention.
A main objective of the present invention is providing a keyboard having a water-proof and dust-proof function and a key structure thereof.
To achieve the foregoing objective, the present invention provides a key structure, including:
a fixed plate;
a key pedestal, fixedly disposed on the fixed plate and having a key support shaft;
a keycap, coupled to the key support shaft;
a flexible protection cover, disposed on the fixed plate, including:
In the foregoing preferred embodiment, the hollow protrusion structure bends inwards at an end of the opening and forms an extending part extending towards the keycap.
In the foregoing preferred embodiment, a material of the flexible protection cover is: rubber or silicon.
In the foregoing preferred embodiment, at least one stop structure is provided on a circumferential surface of the key pedestal.
In the foregoing preferred embodiment, the fixed plate is provided with a fixing hole, the key pedestal passes through the fixing hole, and the stop structure presses against a surface of the fixed plate.
In the foregoing preferred embodiment, at least one bent structure is provided at a connection between the hollow protrusion structure and the sheet-like body, and the at least one bent structure is configured to cover the stop structure.
The present invention additionally provides a keyboard, including:
a lower cover;
a fixed plate, fixedly disposed on the lower cover;
a plurality of keys, disposed on the fixed plate, and each being provided with:
a key pedestal, fixedly disposed on the fixed plate and having a key support shaft; and
a keycap, coupled to the key support shaft;
a flexible protection cover, disposed on the fixed plate, including:
a sheet-like body, configured to couple the fixed plate; and
a plurality of hollow protrusion structures, formed on the sheet-like body, the plurality of hollow protrusion structures each being configured to partially cover the key pedestal, an opening being provided at a top end of each of the hollow protrusion structures, and the key support shaft being correspondingly configured at a position of the opening; and
an upper cover, disposed on the sheet-like body and assembled to the lower cover, a recess being provided on the upper cover, and the hollow protrusion structures being located in the recess.
In the foregoing preferred embodiment, the hollow protrusion structure bends inwards at an end of the opening and forms an extending part extending towards the keycap.
In the foregoing preferred embodiment, a material of the flexible protection cover is: rubber or silicon.
In the foregoing preferred embodiment, at least one stop structure is provided on a circumferential surface of the key pedestal.
In the foregoing preferred embodiment, the fixed plate is provided with a plurality of fixing holes, the key pedestal passes through the fixing holes, and the stop structure presses against a surface of the fixed plate.
In the foregoing preferred embodiment, at least one bent structure is provided at a connection between the hollow protrusion structure and the sheet-like body, and the at least one bent structure is configured to cover the stop structure.
In the foregoing preferred embodiment, the keyboard further includes a switch circuit board, the switch circuit board being disposed between the lower cover and the fixed plate.
In the foregoing preferred embodiment, a limit column is provided at a bottom end of the key pedestal, a limit hole corresponding to the limit column is provided on the switch circuit board, and the limit column passes through the limit hole.
More detailed descriptions are made with reference to the examples of the embodiments and the accompanying drawings, to make advantages and features of the present invention and the method to implement the present invention easier to understand. However, the present invention may be implemented in different forms and it should not be understood that the present invention can be implemented only by using the embodiments described herein. On the contrary, for persons of ordinary skill in the art, the provided embodiments will make the disclosure more apparent and comprehensive and completely convey the scope of the present invention.

Referring to
The sheet-like body 21 of the flexible protection cover 20 is coupled to the fixed plate 30, the hollow protrusion structure 22 is configured to partially cover a surface of the key pedestal 41, and the key support shaft 413 is correspondingly configured in the position of the opening 23. The keycap 42 fits with the key support shaft 413 by means of the fit structure 421, to be coupled onto the key pedestal 41. In this embodiment, the key 40 is a mechanical key, and when a user presses the keycap 42, the keycap 42 moves downwards to push the key support shaft 413, so that a linkage (not shown) in the key pedestal 41 moves downwards, to drive an elastic part (not shown) to drive the switch circuit board 90 to output a corresponding key signal.
A bent structure 221 with a shape corresponding to that of the stop structure 412 is provided at a connection between the hollow protrusion structure 22 and the sheet-like body 21, so that the bent structure 221 may completely cover the stop structure 412. In addition, the hollow protrusion structure 22 bends inwards at an end of the opening 23 and forms an extending part 222 extending towards the keycap 42. By disposing the extending part 222, the skirt structure 422 of the keycap 42 may completely shield the opening 23 of the hollow protrusion structure 22, so that water drops or dusts are prevented from entering the opening 23 from side angles. In this way, the water-proof and dust-proof efficacy of the flexible protection cover 20 can be improved.
As compared with the existing technology, the water-proof and dust-proof efficacy of the keyboard and the key structure thereof provided in the present invention can be improved by using a flexible protection cover. Therefore, the present invention is a creation of extraordinary industrial value.
Any modification made to the present invention by persons skilled in the art by means of technical measures shall fall within the protection scope of the claims.
