Technical Field
The present invention relates to a keyboard with a mute function and a key structure thereof, and more particularly, to a keyboard and a key structure thereof, which use an elastic buffer layer as a contact buffer to achieve mute and shock absorption.
Background
Modern people often use computers in daily life, and a keyboard is an important role of a desktop computer (or a Personal Computer (PC)) or a notebook computer, so as to provide a user with character input or operation control. Generally, a keyboard is composed of a plurality of keys, each of which is arranged at a specific position. In addition, many electronic devices or motor operating devices are provided with related keys as operation interfaces for various designated functions.
In order to provide user input and control, the key has the characteristics that the original position of the key can be restored after the key cap is pressed once, and a trigger signal can be generated in response to the pressing. Therefore, the user can press the same key next time, and the hand feeling of successful touch and press of the user can be increased through the compression and rebound mechanism of the key.
In the prior art, the different types of keys are classified into a Mechanical (Mechanical), a Membrane (Membrane), a conductive rubber (conductive rubber), a contactless electrostatic capacity (Capacitive) type, and the like by the type of a Switch (Switch) therein. Different types of keys have different service lives, touch feeling or manufacturing costs.
In addition, the design of the scissor-foot structure arranged below the keycap can average the force application direction when a user presses the keycap, and the design of the scissor-foot structure is matched with the rebound function generated by an elastic element (such as a spring or a Rubber Dome) to enable the key to be operated repeatedly. If the scissors structure is not provided and only the resilience of the elastic element is utilized, the key with a larger key cap area on the keyboard is easily formed due to uneven force application, such as multiple keys like a Space key (Space), an input key (Enter), a Shift key (Shift), a case change key (Caps Lock) and the like.
On the other hand, a balance bar can be used to match the scissors structure for longer or larger keys. The balancing rod is a long rod shaft and is correspondingly arranged below the keycap and around the scissor leg structure, and the keycap can be driven to integrally and evenly move downwards by pressing the upper part so as to avoid the situation of pressing and deviating the inclined keycap with one side higher and the other side lower.

However, since the related structures are mostly made of hard materials, the keyboards with these structures cannot avoid the generation of noise or sound caused by the impact between the structures when the key caps of the keyboards are pressed for operation or input; such as contact, abutment or collision between a
Therefore, how to solve the problem of the prior art is the main objective of the development of the present invention.

Furthermore, with current technology, the thickness of the component produced by mold ejection using thermoplastic materials is large, at least about 0.6 millimeters (mm). Therefore, the buffer layer and the key structure formed by the buffer layer may not be suitable for a general thin keyboard. The present invention further contemplates other ways to form and dispose the buffer layer.
As mentioned above, in an embodiment, the buffer layer may be formed by using a material such as silicon gel, and the buffer layer is disposed on the bottom surface and the flange in a hot press cladding manner. In detail, in the process, a harder material can be firstly injected in a die to form the keycap, and the silica gel material is hot-pressed in a hot press with a corresponding die to form a required plane part, a protruding part and a combining part, and is mutually welded with the keycap to complete the arrangement of the buffer layer. The cushioning layer of silicone gel may have a relatively thin thickness, such as about 0.3 millimeters (mm) in plan view.
If the cushioning layer formed by hot pressing is still too thick, in another embodiment, a material such as rubber may be used to form the cushioning layer, and the cushioning layer is disposed on the bottom surface and the flange by spraying. In detail, the key cap may be formed by injecting a hard material into a mold, and the rubber material is prepared in a liquid state and sprayed on the bottom surface and the flange of the key cap to form the required flat portion and the protrusion. The combining part is longer, so that the combining part can be adhered to the plane part and the protruding part after being formed by a mold, thereby completing the setting of the buffer layer. The rubber lacquer-sprayed cushioning layer may have a thinner thickness, for example, a flat portion of about 0.1 to 0.2 millimeters (mm).
In summary, the keyboard with a mute function and the key structure thereof provided by the present invention effectively utilize the characteristic of the elastic material of the buffer layer, that is, the elastic material can be used as a contact buffer in response to the deformation generated during pressing, thereby achieving the mute and shock absorption functions and purposes. In addition, the elastic material of the buffer layer also has the characteristics of abrasion resistance, durability, deformation resistance and the like, so that the arranged related elements are not easy to damage caused by collision. Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and to achieve the object of the present invention.
Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto. Various modifications and alterations may be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention is subject to the protection scope of the appended claims.
