Abstract
An embodiment of a hinge assembly includes a main body defining a shaft hole, a connecting shaft including an inserting end rotatably received in the shaft hole, and an expansion member forming a tapered portion and axially positioned in the shaft hole. An end surface of the inserting end toward the expansion member defines a tapered hole corresponding to the tapered portion, and the tapered portion is pressed into the tapered hole to expand the inserting end to resist the inner surface of the shaft hole, thus rotatably connecting the connecting shaft to the main body.
Claims14
A hinge assembly comprising:
- a main body defining a shaft hole;
- a connecting shaft comprising an inserting end rotatably received in the shaft hole;
- and
- an expansion member forming a tapered portion and axially positioned in the shaft hole;
- wherein an end surface of the inserting end toward the expansion member defines a tapered hole corresponding to the tapered portion, and the tapered portion is pressed into the tapered hole to expand the inserting end to resist the inner surface of the shaft hole, thus rotatably connecting the connecting shaft to the main body.
An electronic device comprising:
- a base;
- and
- a lid pivotally connected to the base via at least one hinge assembly, the at least one hinge assembly comprise:
- a main body defining a shaft hole and secured to the base;
- a connecting shaft having an inserting end rotatably received in the shaft hole and secured to the lid;
- and
- an expansion member forming a tapered portion and axially positioned in the shaft hole;
- wherein an end surface of the inserting end toward the expansion member defines a tapered hole corresponding to the tapered portion, and the tapered portion is pressed into the tapered hole to expand the inserting end to resist the inner surface of the shaft hole, thus rotatably connecting the connecting shaft to the main body.
