Description

Buttons with a sense of pressing paragraphs

technical field

The invention relates to a button, in particular to a button with a sense of pressing a paragraph.

Background technique

The keyboard keys of various 3C electronic devices are becoming thinner and thinner, and the overall height is greatly reduced. The traditional large-scale mechanical keyboard can no longer match this thin design trend. Therefore, the common design method is to use a button structure with a smaller amount of pressing or It's a touch button.

The user often cannot clearly feel the pressing feedback when pressing the above-mentioned button structure or the touch-sensitive button. As a result, during actual operation, the user may not be sure whether the pressing operation is completed, causing operational troubles.

For example, China’s patent application No. 201610802371.0 discloses a keyboard switch that can improve the pressing tactility. It uses the guiding slope of the base and the elastic part to cooperate with the action of the pressing block to realize the feeling of touch and sound during the pressing process. However, the aforementioned elastic member can only be simply put into the base, and cannot be positioned stably and generate elastic force, which easily affects the normal operation of the overall keyboard switch.

Contents of the invention

Therefore, the main purpose of the present invention is to provide a key that has a better and clearer sense of pressing steps, and has a thinner overall size, a simpler and more stable structure, and various additional properties that can be flexibly set.

In order to achieve the above object, the present invention provides a button with a sense of pressing paragraphs, which includes a bearing assembly, a word key, a linkage unit, a driving member, an elastic member, and a reset member; the word key is movably arranged Above the carrying component, the linkage unit can movably connect the word key and the carrying component, and the word key can reciprocate between an unpressed position and a pressed position relative to the carrying component; the driving member has a first A guide surface and a second guide surface, the driving part is movably located between the bearing assembly and the key, and the driving part moves back and forth with the key; the elastic part has a body, and the body is positioned In the bearing component or the linkage unit, the elastic member corresponds to the position of the support part and is located at the position corresponding to the first guide surface or the second guide surface; the reset member is arranged between the bearing component and the key Thereby, when the word key drives the driving member to move from the unpressed position to the pressed position, the elastic member corresponding to the position of the supporting part is pushed by the driving member and deviates out along the first guide surface The driving member, at a position corresponding to the second guide surface, produces a feeling of pressing a paragraph; and when the word key moves to the pressing position, the reset member can directly move the word key from the pressing position to In the unpressed position, the elastic member corresponds to the position of the supporting portion and is pushed against by the driving member and is deflected back to the position corresponding to the first guide surface along the second guide surface.
