Eletronic device

An electronic device, comprising:

• a first component including a first housing and a protrusion element, wherein the first housing has a first cover plate, and the protrusion element is disposed on the first cover plate;
• and
• a second component rotationally assembled with the first component along a first direction, wherein the second component includes a second housing, an elastic structure, and a switching element;
• wherein the elastic structure and the switching element are disposed in the second housing, the elastic structure includes an elastic post, the second housing includes a second cover plate having a through hole, and one part of the elastic post passes through the through hole and is exposed on the second cover plate;
• wherein the protrusion element moves along the first direction relative to the elastic structure, such that the elastic post is squeezed by the protrusion element to move along a second direction and presses the switching element, and the first direction is perpendicular to the second direction,
• wherein the second component further includes a circuit board, the circuit board is disposed in the second housing, and the switching element is connected onto the circuit board;
• wherein the elastic structure further includes a body portion and an elastic extending portion, the elastic structure is disposed between the circuit board and the second cover plate, and two ends of the body portion are respectively connected to the second housing and the circuit board;
• wherein the body portion surrounds the elastic post to form an accommodating cavity, the switching element is located in the accommodating cavity, the elastic extending portion is connected between the elastic post and the body portion, the elastic post has a head portion, and the head portion passes through the through hole and is exposed on the second cover plate.
