Abstract
The utility model discloses a special piezoelectric type key structure which comprises a key, an elastic piece and a base, wherein the key is installed on the elastic piece, the bottom end of the elastic piece is fixedly installed on the base, the elastic piece enables the key to separate from the base by the elastic restoring force of the elastic piece, a piezoelectric crystal located between the key and the base and only in match and contact with the key is fixedly installed at the top of the base, the external force applied on the key conquers the elastic restoring force of the elastic piece to enable the key to move towards the piezoelectric crystal to touch the piezoelectric crystal and enable the piezoelectric crystal to deform by the extrusion of the key under external force. The special piezoelectric type key structure is reasonable in structure and much higher in working reliability.
Description
Technical field
The utility model belongs to the improvement of press-key structure, particularly extraordinary piezoelectric type press button mechanism.
Background technology
Facts have proved, although existing conventional keys structure super quality and competitive price, its structure setting is still unreasonable, and especially the irrational mix design causes existing conventional keys functional reliability not high.
The utility model content
The purpose of this utility model is to provide a kind of extraordinary piezoelectric type press button mechanism, and it is rational in infrastructure, and functional reliability is higher.
the purpose of this utility model is achieved in that a kind of extraordinary piezoelectric type press button mechanism, comprise button, elastic component and base, button is arranged on elastic component, its bottom of elastic component is packed on base, elastic component relies on its elastic restoring force that button and base are separated from each other, be fixedly mounted with the piezoelectric crystal that matches and contact with button between button and base and only in base top, putting on external force on button overcomes the elastic component elastic restoring force and makes button move to touch piezoelectric crystal and make piezoelectric crystal be subjected to by the extruding of the button of External Force Acting and be out of shape towards piezoelectric crystal.
The utility model utilizes piezoelectric crystal to produce the principle of piezoelectric effect because of compressive deformation, when button is pressed down by External Force Acting and is pushed piezoelectric crystal, piezoelectric crystal just can compressive deformation and is produced piezoelectric signal, namely because piezoelectric effect output has voltage or current signal, facilitate the respective electronic device will receive, recognize above-mentioned piezoelectric signal and corresponding output order.The utility model is rational in infrastructure, and functional reliability is higher.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
a kind of extraordinary piezoelectric type press button mechanism, as shown in Figure 1, comprise button 1, elastic component 2 and base 4, button 1 is arranged on elastic component 2, elastic component 2 its bottoms are packed on base 4, elastic component 2 relies on its elastic restoring force that button 1 and base 4 are separated from each other, be fixedly mounted with the piezoelectric crystal 3 that matches and contact with button 1 between button 1 and base 4 and only at base 4 tops, putting on external force on button 1 overcomes elastic component 2 elastic restoring forces and makes button 1 move to touch piezoelectric crystal 3 and make piezoelectric crystal 3 be subjected to by button 1 extruding of External Force Acting and be out of shape towards piezoelectric crystal 3.
