KEY STRUCTURE ASSEMBLY, ASSEMBLING METHOD, AND ELECTRONIC DEVICE HAVING KEY ASSEMBLY

摘要

Provided in the present invention is a key structure assembly, comprising a housing, a key body, an elastic member, and a switch control circuit. The switch control circuit is disposed in the housing, and comprises a switching element and a circuit board electrically connected to the switching element; the housing comprises an upper housing and a lower housing detachably connected to the upper housing and forming a closable accommodating space at the lower part; the key body has a pressing portion and a shaft portion integrally formed at the lower end of the pressing portion, the pressing portion is exposed to the outside of the housing and is connected to the elastic member from the lower side to be flexibly connected to the upper surface of the upper housing, the shaft portion passes through a through hole of the upper housing and is aligned with the switching element, and when a force is applied to the pressing portion, the pressing portion resists against the stress of the elastic member and interlocks with the shaft portion so that the shaft portion mechanically extends downwards and the switching element is thus triggered. The totally-enclosed waterproof key structure assembly provided in the present invention has the good closure property, independence, mechanical property, and air tightness, and can effectively improve the operability, safety and maintenance convenience of a product.
