Key structure and mobile terminal

Abstract

The invention provides a key structure and a mobile terminal. The key structure comprises a key and a supporting part, wherein a conducive base is arranged on the inner side face of the key; the supporting part is positioned in the mobile terminal; the first end surface of the supporting part is in contact with the conductive base; the second end surface of the supporting part is in contact with a switch in the mobile terminal, wherein the midperpendicular of the first end surface and the midperpendicular of the second end plane are non-collinear. According to the technical scheme, the non-collinear conductive base and switch are connected together through the supporting part; the force on the conductive base is smoothly transmitted to the switch by the supporting part, so that the switch can be moved to a preset position to further switch on a switch circuit; and in addition, the supporting part is elastic and can enable the key to spring back rapidly, so that the user experience is improved.

Description

technical field [0001] The present invention relates to the field of electronic products, and more specifically, to a button structure and a mobile terminal. Background technique [0002] At present, the keys of most mobile terminals (such as smart phones) are composed of key caps and key silica gel with a conductive base, and the key is connected to the key switch (Switch) through the key connector. In the process of pressing, push the button switch to move inward to a certain stroke (generally 0.2mm), so that the switch circuit of the main board is turned on. like figure 1 As shown, in the current mobile terminal, the vertical line of the conductive base section and the vertical line of the contact surface of the switch are set on the same straight line, so that when the button is pressed inward, the button connector can be pushed inward, so that the switch Move a certain distance inward to turn on the switch circuit of the main board. However, due to factors such as mo...

Problems solved by technology

However, due to factors such as mobile phone ID (Industrial Design, Industrial Design) definition and stacking design inside the mobile terminal (such as a smart phone), the conductive base vertical line of the button of the mobile terminal (such as a smart phone) is often separated from the vertical line of the main board switch. Not on the same straight line, so that the contact surface of the two devices is eccentric, and the eccentricity will cause poor contact between the button, the button connector and the button switch, and when the button is pressed to make the button switch move inward, it will cause the button. And the key switch is unevenly stressed. On the one hand, the key switch cannot be moved to the predetermined position, so that the switch circuit cannot be turned on. user experience
