Problems solved by technology

Although the hinge structure can realize the rotation of the display screen, however, after a period of use, the components of the hinge structure are easy to loosen. At this time, when the display screen is adjusted to a certain angle, due to insufficient frictional torque, Under the gravity of the cover body, it cannot stay firmly and cannot continue to be used

Embodiment Construction

[0011] A preferred embodiment of the present invention discloses a hinge structure, which is suitable for electronic devices including two components, such as notebook computers, digital cameras (Digital Camera, DC) and digital video cameras (Digital Video, DV). In this embodiment, a notebook computer is taken as an example for illustration.

[0012] see figure 1 , the notebook computer includes a body 10 , a cover 20 and a hinge structure 30 connecting the body 10 and the cover 20 . exist figure 1 In the state, the cover body 20 is opened at a certain angle relative to the main body 10 .

[0013] Please refer to Fig. 2, the hinge structure 30 described in this preferred embodiment includes a bracket 302, a rotating shaft 304, two fixed wear plates 306, 307, two movable friction plates 308, 309, and two pairs of elastic plates 310, 311 , a washer 312 and a locking member 314.

[0014] The bracket 302 includes a fixing portion 3022 and a connecting portion 3024 perpendicula...

Abstract

The invention discloses a hinge structure, which is suitable for electronic devices such as the notebook computer comprising two components. The invention comprises a support, a rotation axis, two movable friction plates, two fixed wear plates, an elastic component and a locking firmware. One movable friction plate and one fixed wear plate are arranged at one side of the support and the other movable friction plate and the other fixed wear plate are arranged at the other side of the support. In addition, each movable friction plate is arranged closely to the corresponding fixed wear plate. The elastic component is sheathed on a rotation axis to provide axial force. The movable friction plates are sheathed on the rotation axis and can not rotate. The support and the fixed wear plates are sheathed on the rotation axis rotatablely. The locking firmware is arranged at one end of the rotation axis to prevent the support, the fixed wear plates, the movable friction plates and the elastic component from dropping off the rotation axis. One movable friction plate and one fixed wear plate are respectively arranged at the two sides of the support of the hinge structure; thereby double-faced friction is formed at the two sides of the support, which can increase friction torque effectively.

Description

technical field [0001] The present invention relates to a hinge structure, in particular to a hinge structure suitable for portable electronic devices such as notebook computers. Background technique [0002] With the wide application of computers, their functions are increasing and perfecting day by day, and their volumes tend to be thinner and lighter. Desktop computers are bulky and rather heavy, and are extremely inconvenient to carry, so notebook computers can be widely used. Notebook computers are small in size and light in weight, and are widely accepted in the market, especially by people who travel frequently. Notebook computers generally include a body and a cover, on which the display screen is arranged. In order to provide a better viewing angle for the display screen, it is usually necessary to rotatably or swingably connect the cover to the body through a hinge structure. [0003] An existing hinge structure includes: a fixed seat, a pivot, a washer and an el...
