Hinge and tablet computer

Abstract

The present invention discloses a hinge and a tablet computer. The hinge is applied to the tablet computer. A back cover of the tablet computer comprises an upper back cover and a lower back cover. The hinge comprises an upper support frame fixed in an inner side of the upper back cover and a lower support frame fixed in an inner side of the lower back cover, the lower support frame is driven by the lower back cover to rotate relative to the upper support frame, and the rotation center of the lower support frame is positioned at an outer side of the back cover. Due to the fact that the rotating shaft center of the rotation of the lower support frame relative to the upper back cover is disposed at the outer side of the back cover, interference between the lower back cover and an edge of the upper back cover is prevented when the lower back cover rotates, and an edge of the lower back cover cannot enter the inside of the tablet computer due to rotation. So the tablet computer equipped with the hinge is compact in structure, and the upper and lower back covers are tightly abutted.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a hinge for a tablet computer and the tablet computer. Background technique [0002] At present, a tablet computer with a flip back cover has gradually become an industry trend of a two-in-one tablet notebook. The flip back cover can bring a variety of use modes to the tablet notebook, such as a standing mode, a tent mode, and the like. [0003] Such as figure 1 with image 3 As shown, the back cover of the tablet computer with a flip back cover includes two parts, one part is the upper back cover 100 fixed on the back of the tablet computer, and the other part is the lower back cover 200, which can rotate at a certain angle relative to the tablet computer . By rotating the lower back cover 200, the tablet computer can be kept in different standing postures, thereby satisfying users' requirements for different usage angles of the tablet computer. [0004] Such as figure 2...

AI Technical Summary

Problems solved by technology

[0005] 1. When the lower back cover 200 is closed (the lower back cover 200 and the upper back cover 100 are on the same plane), a certain gap must be maintained between the lower back cover 200 and the upper back cover 100, otherwise, when the lower back cover 200 rotates, the lower back cover 200 The edge will interfere with the edge of the upper back cover 100, but this gap will greatly compromise the aesthetics of the tablet

[0006] 2. When the lower back cover 200 is opened (rotated at a certain angle), the edge of the lower back cover 200 will turn to enter the interior of the tablet computer. Therefore, a certain avoidance space needs to be reserved for the edge, which will inevitably increase the size of the tablet computer. volume, contrary to the requirement of compactness

[0007] In order to solve the above problems, technicians have added a mutual-limiting structure of special-shaped grooves on the basis of the above structure, but the manufacture and assembly of this structure is difficult, the structure and function are single, and automatic locking and unlocking cannot be realized
