Description

Foldable electronic device

Technical Field

The invention relates to the technical field of computers.

Background

Generally, a notebook computer or a foldable electronic device is designed to connect a display screen and a system host respectively by a pivot mechanism, so that the display screen can be rotated to a position covering the system host for folding or carrying about, or rotated to a position extending a certain angle (e.g. 120 degrees) relative to the system host for operation.

The pivot mechanism is a very important component, which has a great influence on the shape of the product, especially on the appearance design. Taking a foldable electronic device as an example, two parts of a traditional rotating shaft rotating around a shaft are respectively fixed on a base and a display screen, and the position of the traditional rotating shaft relative to the shaft is kept unchanged, so that a product is in a single form.

More importantly, the current trend is for foldable electronic devices to be thinner and thinner, and conventional hinges impose some limitations in this regard. Both the product form and the design of the appearance have high requirements, and therefore, a design is required to reduce the restrictions on the product form and the design of the appearance.

A further improvement of the present invention is that the connecting end is connected to the first connecting member by an eccentric, the distance of the connecting end from the support end gradually increasing as the first body unfolds relative to the second body; when the first body is folded relative to the second body, the distance between the connecting end and the supporting end is gradually reduced.

The invention has the further improvement that the first connecting part comprises a first gear sleeved on the rotating shaft and a second gear connected with the connecting end of the foot pad, and the first gear and the second gear are in transmission connection through a rack.
