Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
The elastic force of the button on existing mobile terminal or mobile terminal model is all fixing, it is impossible to
Meet the different crowd demand to button key spring, the invention provides one to solve the problems referred to above
Elastic force turnable keys.
As Figure 1-3, elastic force turnable keys of the present invention includes press button mechanism 11, metal dome
5, it is provided with the governor motion 12 of boss 121, described governor motion is provided with regulation switch, institute
State the adjustment structure distance by metal dome described in described regulation switch-mode regulation Yu described boss, wherein,
Described press button mechanism includes that button 7, the rosette 6 being arranged on described button surrounding and button prop up
Frame plate 8, described button and described rosette are arranged on described key support plate side, and described button props up
Frame plate opposite side is additionally provided with the silica gel piece 4 being connected respectively with described button, described rosette, described
Silica gel piece contacts connection with described metal dome.
The resilience force (i.e. pressing rear self-return) that metal dome is the most stable, and there is more preferable hands
Sense, longer life-span, can also indirectly improve the production effect of all types of switches using conducting film
Rate, has the life-span of overlength simultaneously, it is possible to bring the sense of touch of high-quality to feed back to operator.Metal dome
