Abstract: An electronic assembly including an electronic device and a stylus is provided. The electronic device includes a housing having a receiving groove and an opening, the opening communicating with the receiving groove, and a first connecting element disposed around the opening. The stylus includes a sleeve and a pen rod. The sleeve has a second connecting element and corresponds to the receiving groove. The second connecting element is combined with the first connecting element to fix the sleeve to the housing. The pen rod is slidably disposed in the sleeve and has a first end and a second end opposite to each other, and a third connecting element located at the first end.

Abstract: An electronic device includes a body, a stand and a sliding member. The stand is rotatably connected to the body. The sliding member is slidably disposed on the body and has at least one stopping portion and at least one pushing portion. When the sliding member is located at a first position, the stopping portion interferes with the stand to stop the stand from expanding from the body. When the sliding member slides relative to the body to be away from the first position, the stopping portion releases the stand and the pushing portion pushes the stand to drive the stand to rotate and expand from the body.

Abstract: A pivot structure includes a base, a bracket, an elastic component, and a positioning assembly. The bracket is rotatably connected to the base. The elastic component is disposed on the base. The positioning assembly includes an elastic clip and a pillar. The elastic clip is pivoted to the base and has a first releasing segment and a first positioning segment. The pillar is connected to the bracket and has a second positioning segment. The pillar is rotatably clipped in the elastic clip. The bracket is adapted to be expanded to a first expanding state through an elastic force of the elastic component, so as to drive the second positioning segment to move along the first releasing segment. The bracket is adapted to receive an external force to be further expanded to a second expanding state, so as to drive the second positioning segment to move to the first positioning segment.

Abstract: An electronic apparatus includes a base and an electronic device. The base includes a first main body and at least one first connection portion. The first connection portion includes a rotating component, and the rotating component is pivoted to the first main body and has a driven portion and a positioning portion. The electronic device includes a second main body and at least one second connection portion. The second connection portion includes an elastic component and a positioning trench. The elastic component is connected to the second main body, and the positioning trench is formed on the second main body. When the base supports the electronic device so that the first connection portion is aligned to the second connection portion, the elastic component pushes the driven portion such that the positioning portion is engaged into the positioning trench.
